Hot 97's DJ Funkmaster Flex is gearing up for a big compilation mixtape on April 17th. Flex rounded up some of the biggest rappers in the game, alongside some new-comers, for two different playlists on Who You Mad At? Me Or Yourself?

The two-part mixtape features Lil Wayne, ScHoolboy Q, Waka Flocka, Kirko Bangz, Young Jeezy, A$AP Rocky, Action Bronson, Lloyd Banks, Joey Bada$$, 2 Chainz, Rick Ross, Childish Gambino, Busta Rhymes, J. Cole, Juicy J, B.o.B and Ace Hood--just to name a few.

Check out the tracklist in the gallery above- it may be tricky to read, but we'll update when something better comes along.

The tape will be available through Flex's new app, which dropped today.
