Notes
You can also add items to a playlist in Media Library by dragging items within Media Library or from My Computer. In Media Library, you cannot drag whole items from the Artist or Album categories to a playlist. You can add items to a playlist in Now Playing by dragging an item to the Playlist pane; these items are only added temporarily.
In My Computer, you can also right-click a file, click Add to Playlist, select the playlist, and then click OK.
You can add items to a playlist as long as they are listed in Media Library. For example, you cannot add items that are displayed in the Now Playing category of Media Library if they have not been added to Media Library previously.
You can temporarily add any item from the All Music, All Video, and Other Media categories to a playlist or auto playlist by right-clicking the item, and then clicking Queue-it-up. The item remains in the playlist until you play another item or playlist.
To select contiguous items to add, press and hold the SHIFT key while selecting. To select noncontiguous items to add, press and hold the CTRL key while selecting. Right-click the selected items, and then click AddtoPlaylist.
