text: Every artist can have different songs loaded to play when you go onto their Myspace page.  If you find the song you like (like "Miss Murder" on http://myspace.com/afi), then click on the "add" option underneath the song title on the player.  It will ask you if you are sure you want to change your song to [whatever] and just click yes.  Now every time your profile is looked at on Myspace, that song will play.\n\nWhen an artist takes a song off of their player to add a new one (say, when AFI took Silver and Cold off to add Miss Murder), all the people who had the song on their site now have the box that says "Song deleted by the artist".  Has nothing to do with legality.  Hope this helps.
