"Today we’re happy to announce we’ve converted our entire catalog of over 30 million songs to high-quality AAC audio. Listeners around the world now have four sound quality settings to choose from across iOS, Android, and the web. All Rdio users can choose between data-efficient 64 kbps all the way up to 192 kbps. Rdio Unlimited subscribers now also have the option of listening in pristine-quality 320 kbps. Plus individually select your audio settings for a variety of uses, whether you’re using Wi-Fi or cellular streaming or listening to offline downloads.Our commitment to sound quality also deepens today with our partnership with Bob Weir, the legendary founding member of the Grateful Dead and champion of Musicians for Audio Quality Initiative. To celebrate this milestone, we’re releasing an exclusive catalog of Bob Weir tracks recorded at the Tamalpais Research Institute (TRI Studios), his state of the art studio in Marin County, CA. The catalog features Weir as well as musicians like Dave Schools, Sammy Hagar, and many others."
As I have mentioned in another article, Rdio is a fantastic service. I did like some of the Desktop apps for Spotify, but I mainly listen on iOS and those apps are "desktop-only".
