WWE World Heavyweight Champion Seth Rollins will not be signing a record contract in the near future ... not because he's already under a wrestling deal -- the 29 year-old is just a terrible singer.

Rollins flatly belted out a rendition of "Throne" by Bring Me the Horizon on the new Rock Band game while backstage at RAW -- and the video below of his attempt isn't pretty.

The game was being played for Xavier Woods' YouTube show called UpUpDownDown ... with WWE Superstars Big E, Kofi Kingston, Heath Slater, Brad Maddox and Sasha Banks joining the fun.

Performer of the night? That honor goes to WWE ring announcer Joseann Offerman.

Watch the videos below of their performances and you'll see what we mean.
