Kendrick Lamar has brought Jay-Z on for the remix of "Bitch Don't Kill My Vibe" and that serves two apparent purposes. First and obviously, it makes his spotlight a little brighter, and second, to show how easily he can run lyrical circles around the world's most famous living emcee. Jay-Z seems lost, and Kendrick comfortable as ever. Our only (tiny) gripe is that they didn't include Gaga's vocals on this one. Check it out below.
