First of all, you need to download your music if you want to play it offline.

To download a song, album, or playlist: 

  • Tap the Download button after adding music.

Important: The Sync Library option must be turned on (go to Settings > Music, then turn on Sync Library).

It's also convenient to have your music downloaded always:

  • Go to Settings > Music, then turn on Automatic Downloads.

If you'd like to see the download progress: 

  • While on the Library screen, tap Downloaded Music, then tap Downloading.
