50 Cent won't retire, he "took back" what he said.
Graduation is a much better album than Curtis, imho. Curtis has it's moments, but I don't think 50 can beat his first album. Graduation is an excellent record, although I have to say, collaborating with Lil Wayne wasn't a good move in my book, Lil Wayne is a horrible rapper. His verse in "Barry Bonds" is probably the worst I've ever heard.

Anyway, I'm high and feel like I'm rambling, so I'll stop.
