If you mean a music playlist, what I do is go to playlist.com, sign up for an account so you can save your playlist. then find the music, click embed and chose Gaia choose colors and if you want it to play randomly or in the order they are. copy the url that is generated, then go to edit your profile. create a media module within the page, name the module if you want and paste the generated url into the appropriate section of the module, and it should work. the playlist will stay linked to the one on the playlist website, so you will not have to redo anything if you add or subtract music from the playlist.
