Cookin' Soul's OJAYZIS is, wait for it, a Jay-Z v. Oasis mash up that works really really well. I'm kind of down on mash ups as a genre, but they can be a lot of fun and for some reason I always like Jay-Z mash ups. Maybe that's because I almost always like Jay-Z. Anyway, the whole mix tape is available for free here and it will probably be this weekend's unhealthy music obsession. Enjoy.
