Set up Music for Assistive Access on iPad
A person using Assistive Access on iPad can listen to music from playlists added to the Music app . You can add the Music app when you set up Assistive Access, or anytime after.

Add the Music app
Exit Assistive Access if it’s active.
Go to Settings
> Accessibility > Assistive Access.
Tap Manage Apps, then tap
next to Music.
Tap a playlist to allow it to be played in Assistive Access.
You can create and edit playlists in the Music app. See Create playlists in the iPad User Guide.
Tip: Simplify Music by adding just one playlist. Music opens directly to the list of songs in the playlist when the app is opened.
