DJ Quik challenged Kanye West to get his head out of Kim Kardashian's vagina and start making better music.
Quik's rant happened on Noah Ayala's radio show -- he unloaded on Kanye's 'Life of Pablo' album ... saying fans aren't stupid and can spot a bad product.
Quik, who's promoting his new album, "Rosecrans," claims he wasn't trying to diss Yeezus, but watch the clip ... seems pretty diss-y. Decide for yourself.
Either way ... #ShotsFired
