You may love your Xbox Music app but if you’re still looking for a viable alternative to it, you may want to check out OneMusic from Phillipe Maes.
This full featured MP3 app can access music from your phone as well as from the SD expansion card letting you create cool playlists from your collection. Its clean intuitive interface lets you randomize tunes, repeat music, and sort tracks when you are creating playlists.
The app also offers full album art support but Live Tiles and tag editing features are not part of the current version. Maes is busy working on the two features though, so users should be seeing them in the next update or so. Other limitations of OneMusic is it cannot access Xbox Music, DRM protected files, or work with an Xbox Music Pass.
OneMusic is available on the Windows Phone Store for $1.99 but you can check out the free 5 day free trial before you decide on buying it.
