Just weeks after releasing his new album Droptopwop, Gucci Mane is back with more new music. This time, he's collaborating with Chris Brown on a song called "Tone It Down." The song dropped suddenly very late Monday night with no advance warning. You can check it out below via Spotify.

The track, produced by Hitmaka, features Brown both singing the hook and rapping. If you prefer Tidal, you can find the song here. Or you can check it out on Apple Music and iTunes.

This is Chris Brown's second big surprise release in less than 24 hours. On Monday, he put out a collaborative mixtape with Ray J called Burn My Name. Gucci, for his part, is featured on Big Boi's new album Boomiverse and has just released a movie.
