How do I add more items to a playlist?

To add additional items to a playlist that you have created...

... From an individual item page, you can click on the Select Playlist dropdown, choose the existing playlist and click "Add to Playlist"


or, if you are on the Music list page, you can choose multiple dropdowns to the right of each single you want to add and then choose "Add to Selected Playlists"




Upon returning to your "My Playlist" area, you will see the newly added items in the playlist you selected.
