Import a song from the Music app into GarageBand for iPhone
You can import songs from the Music app on your iPhone into Tracks view. You can import a song to an existing Audio Recorder or Amp track, or have GarageBand create a new Audio Recorder track for the song.
Songs imported from the Music app do not follow tempo changes you make in GarageBand.
Note: You can only import unprotected songs stored locally on your iPhone.

Tap the Loop Browser button in the control bar, then tap Music.
You can search for songs by name, or browse by album, artist, genre, or playlist.
