I can't say just how long I have wanted a streaming service that offered lossless audio (real CD quality).  I first started using streaming services years ago with Rhapsody.  When MOG announced 320K streaming, I switched from Rhapsody.  Then MOG was purchased by Beats and I had to find a new streaming service.  To be honest, none of the 320k streaming services completely filled the void left by MOG.  As a result, I tried Rdio, even though they were using lower bitrates.  It was, by far, the most fully realized service and if it streamed 320k, it would be the replacement.  Guess what, Rdio upped their bitrate to 320K AAC in recent weeks and I dropped Spotify (which I was carrying for sound quality).

I was really in love with all the features offered by Rdio when Tidal came out yesterday.   However, Tidal is lossless and Rdio isn't.  Is that enough to switch streaming vendors?   Well, a comparison is in order.

I have several different audio systems around my house.  As a result, I am always looking for better quality audio.  I am not so worried about sound quality that I am looking at different audio speaker wire or wondering if magic rocks and coloring my CDs will make them sound better, but I do care about sound.  On a scale of disinterested to obsessed, I would fall closer to obsessed than disinterested, but I do own receivers, so I am not a full blown audiophile (by audiophile standards).  

Even though I haven't done an ABX test, I am just going to give Tidal the edge in sound quality.  Some would say it would be a slight edge over 320K on good day.  

Coincidentally, I was comparing Norah Jones "Come Away with Me" album that I have in lossless format on my computer with Rdio over the last weekend (before Tidal was released).  To my ears, they were slightly different, but I didn't really prefer lossless over Rdio in this case.  I will say that I have always ripped my CDs in lossless because I might hear a difference on some albums and I don't have time to test every single file.

Winner: Tidal

For its part Rdio has numerous paths for curation.  When you listen to music, they automatically build a playlist/station that is made up of your favorites, they provide recommendations similar to artists you like, the list artist similar to artists you have been listening to, they have "dig deeper" recommendations of artists you have listened to, etc...  There are just a lot of ways for them to suggest music for you.    

Tidal is very weak in this area.  They have a section under an individual artist that has similar artists listed.  Rdio also has this feature, but they also have "inspired by"  and "influenced" to give more context into an artist.  Both services appear to use the incredible ALLMUSIC for their Biographies, so no one gets an edge in that area.

Winner:  Rdio (by a long shot)

Tidal has video available.  I found this feature less impressive than I thought it would be.  To find a video, you have to go to a specific artist and then navigate to the video link.   When I tried this, the pickings were slim.  As an example, U2 doesn't have any videos listed.   I thought I would take a look at Miles Davis.  He has videos listed, but they are a photo of Miles with audio playing in the background.  Not very useful.  Bruce Springsteen had some listed, but none of his iconic videos from the 80s.

Tidal has a landscape mode (see pic below) on the iPhone that I found useful.  It allows you to control the song/album that is playing, but it falls short in some ways, too.  You have to put the phone back in portrait mode to get off of that screen if you want to listen to something else.

Another cool feature of Tidal is that it has articles about certain albums and subjects.  For example, there is an article called "15 Ways to Nirvana: Records that shaped the band".    It is like having a subscription to an audio magazine in addition to listening to music.

Rdio has its own set of unique features.  By far the most unique is that ability to remotely control the Rdio desktop app from the iOS app.   Therefore, if you have Rdio running on a computer,  it works just like the iPad/iPhone app.   It will also let you control Rdio running on one iOS device with a separate iOS device.  This is great if you have an old iPhone docked for audio and want to use your iPad to look at the news while listening to music.

Rdio also has a Shazam plug in that helps you build playlists.  It has something called Boil The Frog that is another unique way to build playlists.

One other feature that Rdio has is the ability to set the streaming bitrate independently for cellular and wifi streaming.  I really wish Tidal had this feature.  I don't want to eat through my GBs on my wireless plan too quickly.

They both had the ability to play music based on an artist, but Rdio is more full featured in this area, as well.  With Tidal you can select an artist, or track, and it will play music similar to them.  I found the "track" selections to be less than desirable.  I was playing Joe Henderson's "Double Rainbow" album (which is Bossa Nova music) and a few songs later it picked "Precis" by Sam Rivers to play.  It is more of a "free jazz" (for lack of a better description) styled song.  Not really want I want to hear when I select tracks similar to "Felicidade".  For my tastes, Rdio did a much better job with "track radio".

Also, Rdio has a setting for artist radio that will allow you to play "Artist Only" to "Adventurous" with an option to play music in the middle of those two choices.  With Tidal, the selection is obviously steered toward adventurous.

Another incredible feature on Rdio is the choice to turn on "Autoplay".  This will allow similar music to continue to play after you finish an album.   

Rdio also has the ability to set up a station based on the record label.  A very unique, but often used feature.

Personally, I think Rdio is a better service overall.  I wouldn't mind video, but Tidal needs a better way to find it and they need a better selection.    Tidal's articles look interesting, but I need to read several of them before I decide how useful it is.   Tidal currently costs twice as much as Rdio.  If Rdio had an option to pay $10 extra for lossless, I would pay it.  However, they don't, which is going to make it hard to decide which service will eventually get my money.   Right now, I am currently leaning toward keeping Rdio, but I need to do some back to back listening of the two services over the next month to decide.  I will keep you posted.

A few months back, I had the perfect music streaming app for my needs.  The service was MOG, but in 2012 Beats music bought it.  In May, they killed off MOG and sent invitations for MOG users to enjoy two free months of Beats.  The service is a far cry from the simplicity of MOG and actually removed "artist radio" and "continual play" which were hallmarks of the MOG service.  

There are some great things about Beats, namely their "Just for You " page which has recommendations.  However, the missing stuff was annoying and I started looking for a better option for my needs.

I tried a few services...Spotify, Google Play Music, and Rdio.  I almost ruled out Rdio because I read that they use 192k files, while the other services are using 320k.  I read recently that Rdio is moving to 320k, so I decided to try the service thinking that I could just switch when they completed the move if I liked the service.   Here are the things  I wanted and why I chose Rdio for now, despite the fact that they are using 192k (NOTE:  Rdio now streams in 320k AAC for premium accounts, so this point is no longer a reason to avoid Rdio):

1.  iPad app - Google Play does not have a native iPad app.  This ruled them out from my consideration.  I tried the iPhone app on my iPad and it is ugly compared to iPad native apps.

2.  Desktop app - Another shortfall of Google.  They want you to sign into a browser and I don't want to do that just for listening to music.   Also, Google, as a rule is too creepy for my tastes.  I use some of their services, but avoid them if they don't have a far superior service that makes the creepiness/benefit ratio worth it.

3.  Bluetooth in my car - while they all work for audio, Rdio has the only implementation that works perfectly for seeing the current song that is playing and album art on my nav screen.  Beats has the worst integration and I contacted them, but it isn't fixed.  It was the main, but not only, reason I ruled them out.  I should point out that my car may need a firmware update, but it doesn't explain why Rdio is the only one that works properly.

4.  User Interface -  This is personal, but Rdio has the best looking user interface for my taste.  It looks clean and it is easy to get to anything you want, quickly.   Beats looks great, but it takes forever to get to basic features like new releases. Spotify has a photo of hands reaching up at a concert on a dark background, I prefer the light blue used by Rdio.   

5.  Autoplay - I don't use playlists.  I don't want to spend the time choosing music when I would rather just let the service I am paying for do that for me.   With Rdio (like MOG), I can choose an album and it will continue to play similar music (slowly moving to my regular favorites) when the album is over without direct intervention from me.  This was a major feature that I use at work every day and I did not see the feature on Spotify.  

6.  Artist radio - On the Rdio desktop app, you can choose to play one artist or mix in more artists using a scale from "Artist only" to "Adventurous".  It is similar to MOG's slider and I could not find another service with anything similar.   I don't believe their iOS app has the same level of choice (Edit: This feature is available on the iPhone, it isn't easy to find, so I may have missed it or they added the feature after I wrote this original article) , but you can log into a browser, pick "artist only" and if your iPhone is currently playing it will switch to artist only.  I can't  stream using my computer at work, but I can log in and make this change.  Not perfect, but the closest thing to MOG.

Google's best feature is the integration of your own library with theirs.  While I liked this feature, it offers minor convenience when compared to iTunes Match (which I currently have).  The upside to iTunes Match is that it is integrates into Siri, so I would rather use it for my own music on the road.  At home, I would rather use my iTunes library that houses my lossless audio collection.  Also, the downside to having your library in the app is that it takes a lot longer to load the app.  I have around a 20,000 file library to load, so that could be the reason, but when I want to listen in my car, I don't want to wait to listen.  In fact, I usually like to start the album before I drive the car.  

Rdio will scan your collection, but they don't copy up files that aren't in their library.  Therefore, I can't access the Beatles music I have in my library using their app, like I could with Google.  Not really a big deal for me, though.

I was intrigued with Spotify Connect when I first heard about it.  I thought it would be great to be able to have Spotify running on a computer while controlling what was playing via the Spotify app on my iPhone.  However, Spotify Connect is not available on computers at this time.  It only works on mobile platforms, which I find much less useful.

Rdio, on the other hand , already has a similar feature that does work on their desktop apps, mobile to mobile, or on their web interface.  While I did not even consider this an important feature, after using it, it helped push me over the hump to switch to Rdio.  Here is the way I use it at home and I am not suggesting that everyone has a similar setup, but you could probably find a use for it.

A list of stuff that can be used from my current setup:

1.  Mac Mini (any computer will work) wired directly to the internet
2.  Mini is hooked up directly to a DAC using optical out and to a Denon receiver using HDMI (see more about my setups on my other webpages)
3.  Airplay Express units  (used first generation versions can usually be found for around $50) around the house (some wired, some wifi)
4.   iOS devices and laptops around the houses
5.  Roomie Remote, Airfoil and Airfoil Remote app, Splashtop

Note:  I get paid commissions for purchases made through any links to Amazon products in this post.

How I use Rdio with this stuff:

1.  I usually keep Rdio up on the Mini, but I can use Roomie Remote app (or Splashtop) to launch it using my iPhone/iPad.  

2.  Once it is launched, I can use Splashtop or AF Remote app to hit play.  AF Remote will also allow you to see album art or change songs using an iOS device.  Splashtop simply takes over your desktop, so it has the same functionality.

3.  Once Rdio is playing on the desktop, I can send that signal directly to my Denon receiver via HDMI or to any or all Airport Express units using Airfoil or my Mac's audio settings (for PC you need Airfoil or a similar program to do this).  I prefer Airfoil since I can pick the Airplay device from the AF Remote app.  Below are some screenshots from the AF Remote app (you would have to scroll down on the app to get more Airplay devices since they don't all fit on the first page):

Once you have it playing on the Airplay unit(s) or direct connection of your choice, you can control what is playing using Rdio's app.  It has complete control of the desktop app, so you can search for artists, start new albums, playlists, etc. and play them directly from the computer.

The advantage this has over just using Airplay directly from iOS is that it most likely will use less of your iOS device battery since it is only working as a remote.  Actually, once you have it playing, you can just turn the phone off.  Secondly, if your Airplay device is on wireless, you don't need to use wifi to your iPhone and back to your Airplay device.   You are only sending it from the computer (which is hooked to ethernet) over wifi.  This should halve your wifi use.  Also, if your Airplay devices are wired, you aren't using wifi at all, except for remote control.  This is nice if you have poor wifi reception.    (I should mention that these are nice features to have if they are given to you free as part of an app.  I would not pay extra for this ability because it isn't a necessity in my setups.  Sonos has similar functionality (even without a computer) if you don't mind giving up the Rdio user interface for the one Sonos wants you to use and you don't mind paying a King's ransom for the functionality). 

Here are some pics of Rdio's iOS interface working as a remote.  As you can see, you can use it as a remote or change the Rdio audio stream to switch directly to the iOS device:

Notice the choice of "artist only" or "adventurous" and the ability to "tap to play here instead" .  Also I like the way the top of the screen will use the same colors that are in the album cover:

You have similar control when you are using a laptop or another computer in the house while using the main computer to play the music.  For example, I use the Mac Mini to run the app and listen to music while I am on the couch using a laptop.  The laptop can use the Rdio app to control what is playing on the other computer, but I like the way it will actually show the title of a new song from the top of the screen, even though the song isn't originating from the laptop.

My main issue with Rdio is the fact that they are using 192k files.  I haven't done a comparison of them vs the 320k services, but I don't think audio approaches transparency until you reach 256k (with most music).  However, it isn't so bad that I don't want to listen to it or notice it.    In the winter, I listen to more music inside via headphones, so I may switch to another service if Rdio still hasn't made the switch at that point. *(see note below)

The great thing about these services is that they don't require a long term contract, so I can switch back and forth if I feel like it.  My favorite app for now is Rdio.   Beats could catch up if they tweak a few things.  If Apple adds Beats Music to iTunes and to Siri, it would be a game changer for my usage.   However, I will live with Rdio and hope they change to 320k sooner than later.

(Note: While adding links for services above, I noticed that Spotify has 3 months for the price of 1 month.  I went ahead and signed up for the service, so I will be able to listen to 320k if I decide to use headphones this summer.  While Rdio is my preference, it doesn't hurt to have a fall back for better audio and this price makes it possible.  I will just decide which one to carry forward in September.  Hopefully, Rdio will be using 320k by then.)
