1 Tapping a track name plays it. If it’s stored in the cloud, it’s streamed to your device and cached until your device needs the space for something else.
2 Tap a More Options button (…) to download a track, an album, everything by an artist or in a genre. Tap the progress bar at the top of the screen to pause or cancel.
3 This triangle with a device icon in it identifies tracks that have been downloaded to play offline. The best place to manage them is in Settings > General > Usage > Manage Storage > Music. Cached items aren’t shown there.
4 The Mini Player shows what’s playing. You can pause and resume playback here, or tap the More Options (…) button to do something with the track. Tap the name to open the Now Playing view; its heart button tells Apple you love the track (see page 25).
