Singers, rappers ... Aljamain Sterling will walk to the Octagon to your music -- blasting in the arena, on TV -- at his next UFC title fight, if your song's good enough.
The bantamweight champ is teaming up with 2x Grammy nominee Joyner Lucas ... and they're launching a contest aimed at putting a spotlight on independent artists.
The way it goes ... artists submit a song on Tully, and if Aljo and Joyner like it, you might hear it on the UFC 280 broadcast next month.
