Hello ,
Thanks for using Apple Support Communities.
The following steps are from the GarageBand help section, and explain the 6 step process of importing a song from the Music app.
- To import the entire song, set the current song section to Automatic; otherwise, only the portion of the song that fits the current song section is imported.
- Tap the View button to open Tracks view.
- 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.
- To preview a song, tap it in the list. You can control the preview volume with the slider at the bottom of the list.
- Drag a song left or right to show Tracks view. Align the left edge of the song with the bar or beat on the ruler where you want it to start playing.
