My Playlist

I went to http://www.playlist.com and I was looking for the song from "The Man From Snowy River". THEY DON'T HAVE IT, But I found a place where you can add songs to the site so that the song can be on your playlist. I just can't seem to figure out how to do it. I found some of the songs on a MP3 website and I downloaded them, but I still couldn't get them uploaded onto the playlist site. Do any of you smarties out there know how the accomplish this? Thanks
