Slacker Radio compare (Android)

The best free streaming-radio app on the market, iHeartRadio takes some of (but not all) the best features from TuneIn Radio Pro and combines them with Pandora-like functionality.

With its enormous catalog of on-demand streaming music and its built-in social features for discovering new tunes, Spotify is an absolute must-have for audiophiles and casual listeners alike. But free users, beware of intermittent eardrum-piercing ads.

DoubleTwist is the best music player we've seen on Android. And with the premium AirSync upgrade (highly recommended), it makes it a snap to sync and transfer music between your mobile device and your desktop.

The Rhapsody app is fantastic for listening to your favorite tracks on demand, but it's missing a few key features that desktop users readily enjoy.
