Yeah I have not heard of those bands you mentioned (Brunettes, Big Rock Candy Mountain, Failsafe, Middleman). How it usually works is I'll give the soundtrack a couple of weeks once I have the game in my hands and anything I'm not feeling eventually gets removed from the 2K playlist. It's a small thing, but I'm glad 2K allows us to "uncheck" selections we don't care for (or tire of - like The Game's "Champion" and the Donnie Bravo song from the Draft Combine).
I appreciate 2K's willingness to step away from a full slate of hot rap.
