I wasn't really crazy about any of these CD's. If we're doing strictly hip hop I'd take Lupe's - The Cool over all of them. I thought American Gangster was somewhat overrated and I don't really care for Lil Wayne. If I had to take one of those options I'd go Nas.
Overall I'd have to throw in Vampire Weekend, Raconteurs, REM, and My Morning Jacket before I got to a hip hop album.
