Ask HN: What SEO causes Google to return MP3 links for an artist name?

I'm trying to a help a jazz singer friend with her internet presence. When you google some artists, like "Tierney Sutton" for instance, the first result is a group of 4 links to MP3s. Do you know what SEO makes this happen?

The links are to http://ilike.myspacecdn.com/play/..., but I don't know where those links are coming from. I tried googling for "link:ilike.myspacecdn.com" and got nada.

Links on myspace.com and ilike.com don't look like that.

When I google for my friend, "Kelley Johnson", her web site is the top link, which is great, but I'd like to get those MP3 links to appear also.

Thanks for any ideas or pointers.
