How do I create a playlist and make it available offline?

Make playlists available offline so that you can listen to them without an internet connection: Select a playlist and it will be highlighted in blue. Click the button "Available Offline." The button will change from 'OFF' to 'ON.' Follow the progress of the download in the upper, left-hand corner. As soon as the download is complete, a little symbol will appear on the right, next to the playlist.
