Cee Lo Green -- Endures Street 'Voice' Audition ... from TMZ Photog

Cee Lo Green busted out "The Voice" spinning chair routine on the streets of NYC -- and he did it strictly for one unforgettable performance ... from our camera dude.

Our guy -- whose only previous singing experience (we're being generous) was at his Bar Mitzvah -- attempted to sing the classic 90s song "Cupid" by 112.

It only took a few seconds for Cee Lo to turn around -- just like they do on the show -- and declare ... our photog is 'Voice' ready!! Just not necessarily on Cee Lo's team.
