Kendrick Lamar drops 'To Pimp a Butterfly'

Beyonce, then Drake and now Kendrick Lamar. Everyone is dropping surprise albums and tonight, Kendrick's To Pimp a Butterfly hit the 'nets. It's unclear whether his label planned to release the record a week in advance--according to Top Dawg Entertainment honcho Top, it was a mistake at Interscope--but either way, we get the goodness early.  I'm still giving it a listen, but the last track features a posthumous interview with 2Pac which is awesome and creepy.
