This morning, Kanye West tweeted:

As of 10:30 AM, he's playing the song right here. Big Boy asked him, "Would you say that this record is done?" "We might mix it a few more times," Kanye said. It features Big Sean, 2 Chainz, Travi$ Scott, Gucci Mane, Quavo, Desiigner and Yo Gotti. It's still unnamed, but going by working titles "Round and Round" and/or "Champions."

UPDATE: A radio rip was uploaded:

If Cruel Winter is really about to drop, our theory that Kanye will debut half a new album at Governors Ball this Sunday (6/5) seems just a little less crazy. (Also, G.O.O.D. Music with Pusha T and Big Sean play Summer Jam the same day.)

Kanye also mentions that Cruel Winter will have a 12-15 minute version of Desiigner's "Panda" featuring every G.O.O.D. Music artist (obviously).
