Rdio has been in the Windows Phone 7 marketplace for nearly a year, but has only today, with its 3.0 update, become super useful.
The app has been updated to support Windows Phone 7 Mango, and now supports background playback. Uniquely for a streaming music service on Windows Phone 7 (besides Zune of course), the software also supports synching of music to the device for off-line playback.
The service offers more than 10 million songs and has the following features:
- Access 10+ million songs
- Tons of new albums added every week
- Carry your collection in your pocket
- Sync and play music when you’re offline
- Build unlimited playlists
- Search the entire Rdio catalog
