Amazing app! i got to listen to all my fav songs and artists. the app being free was an awsome touch im confused why not every android phone doesnt have this app. there were only two problem while i was using it. there was tons of lagg every time i would switch songs the song would proboubly be over. the other was that when i would leave the application it would randomly start playing songs so i would shut it down and it would still play random songs.i used this app on the motorola backflip. i do not know if this only happens on the motorola backflip but my aunt has a droid i ran the app and it did the same thing.
