To make a playlist select the songs for the list with the checkboxes to the right of the song titles. If you click the green arrow to play a song you will leave the page to listen but you can use your back button or type Alt-left arrow to return to this page with your selections intact.
After you have selected the songs type the name of your playlist in the Name Your Playlist box using numbers, letters, spaces, dashes, and underscores only. Spaces will be converted to underscores but all spaces and underscores will display as spaces.
Save your playlist by clicking Shuffle or Sort. Shuffle will randomize your songs for you. Sort allows you to control the sort order.
When you are done your playlist will appear on the Get Playlists page and you can use it in a KGPL for Deadheads widget.
