Jay, isn’t an artist and their art like a parent and their children? Isn’t there a natural hierarchical relationship?

http://artist.com/index.html is the artist’s home page.

http://artist.com/song1/index.html is the home page for one of their songs.

Perhaps you’re suggesting that it should be a subdomain? Thus http://www.fred.com is the artist’s primary website, http://singer.fred.com is the site about the artist and http://song1.artist.com is the site about their first song?
