To put songs you need to go to playlist.com and make a playlist by adding your favorite songs. Then when you're done adding songs go back to your account (on playlist.com) and look in the middle of the page next to your playlist: There should be somehtign that says "Add your playlist yo myspaceo r facebook." Click on that. And you'll know what to do from there. But you need to get the code from your playlist.
When you do go back to drawingnow.com and click on "my account" "settings" "profile settings" and paste the code wherever you want the playlist to show up on your profile.
