DoubleTwist burst onto the Android scene as an alternative and bridge for iTunes, but now that Google sells its own tunes, they're getting with the program. The DoubleTwist app can now recognize music from the Google Play Music service and plays them back through its app alongside any of the standard MP3s or other songs you've got stored on your Android devices' internal storage or SD card. There's just one hitch: like Cloud Music Sniper, the updated app can only "see" the music you've selected for offline access in the Google Music  app.
