Chris Brown was at Diddy's Supperclub party in Hollywood earlier this week with Rihanna, and he gave the crowd a preview of a new rap song, which turns out to be titled "Let The Blunt Go," a track that will appear on Funkmaster Flex's upcoming mixtape Who You Mad At? Me Or Yourself?

And tonight, Flex lets Breezy's new League of Starz-produced joint fly as his first offering from the upcoming tape, which will also feature new music by Lil Wayne, The Diplomats, Kendrick Lamar, 2 Chainz, Young Jeezy, Mac Miller, French Montana, Action Bronson, The LOX, Juicy J, Joey Bada$$, and Childish Gambino

Listen below. Also, expect to hear Problem on the final version of this cut.
