Basically you just put this into your user page (or your message wall greeting, depends on where you want the song to play): undefined

For the song URL, it must be a YouTube link. For example, if you want this song to play on your profile/wall: undefined

The "dQw4w9WgXcQ" part comes from that song's URL. It's the part after "?v=" from the link, and that's always the only bit you need.
