cozmo's hook on that hood life off traffic sounds clean. n thats my take on it. i think that if its used on a hook its coo, but if a artist uses it to rap his verse, that shit sounds so whack. i think that weezy n yeezy r more to blame, cuz b4 it was jus t pain ona hook wit autotune. the ones who rap their verses n throw n those gay ass voice hummings b4 they rap, thats jus overkill. it adds a lil more feel to it if its on the hook/chorus.
