Eh, I dunno dude. There isn't a great deal of action games that pump popular tunes as the soundtrack to their works of art. Money issues aside, I think they'd rather just do it themselves. It's one thing to have a theme song or two, but I think composing the majority of the score with pop music is generally frowned upon.
