Yep,
and as you've suggested, sometimes the "out of tune"ness is right for the song.
My singing was once described as aggressively atonal by some one who actually liked the song they were commenting upon.
The tendency, with pitch correction, to squeeze all of the human out of the vocal by making it "perfect", & I don't mean by getting into the robot artefact area, can kill a song stone dead. I know, I've done it more than once.
Most pitch correction doesn't recognize "blue notes" for example. Where would pop'n'rock be without those?
