Kendrick Lamar - Bitch, Don't Kill My Vibe feat. Lady Gaga

Wait, wait, wait. Before you write this off as just Lady Gaga jumping on man-of-the-moment Kendrick's bandwagon (luckily she has since moved on to jumping on confectionery), this demo version of one of the stand-out tracks from Good Kid, M.a.a.d City is actually very good. Plus it shows off a slow jam side to Gaga's vocals in a setting that isn't corrupt with her trying to cop off with an octogenarian. 

The demo was 'leaked' last week by Gaga after none of the pair's collaborations made it onto the album (gutted for you, love). For now we say dim the lights, set the mood, then finish yourself off over the course of the next three minutes.
