Oh, I cant think of the name of it.
I think it was a band called Toto or something like that. I dont know if it was the name of the song, but it went something like "Britney Spears, why won't you date me?" It was a good song too. Too bad I cant remember it
Also:
Limp Bizkit - Just Drop Dead. It's not about, but fueled by Britney (or so says Fred Durst)
