Last night rap-radio icon Funkmaster Flex dropped a new Big Sean track that features a typically entertaining Big Sean verse, as well as one from Kendrick Lamar that basically smashes the entire 2013 rap game as we know it and declares war on literally every other rapper working right now, including calling out by name pretty much every MC he’s been associated with. And he does it with such a maximum of smarts and crazy-eyed flair—shouting out Phil Jackson and declaring that “Instagram can gobble these nuts,” not to mention crowning himself king of both coasts—that it’s hard not to walk away from it at least a little convinced that he might actually be the best right now.

Oh yeah, there’s a Jay Electronica verse too. As per usual, no one but Jay Electronica superfans is impressed.

Listen to Lamar lay waste on everything around him after the jump.
