Repeating a song or playlist
You can repeat a single song, all the songs in your library, or a playlist.
Here are ways to play songs repeatedly:
To repeat the currently playing song, select it and then click the Repeat button twice, so that the number 1 appears.
To repeat all the songs in your library or a playlist, select it and then click the Repeat button once so that it’s highlighted blue.
To turn off repeat, click the Repeat button until it’s no longer highlighted.
You can’t repeat individual songs in a live mix (iTunes DJ).
