Be careful what you wish for. I'm quite particular about pitch when I listen to singing, and if a singer is out of pitch I just can't relax and listen properly. And yet .... recently I listened to some YouTube clips of a well known folk singer. The first ones I listened to, from a live gig, were delightful. Then I found some other clips that were more highly processed and produced, and I'm convinced she'd been auto-tuned. There had been nothing wrong with her pitching in the first place, but somehow the auto-tuning removed the expression and the character from her singing and gave it a less human quality.

Many good singers make tiny variations in the pitch for particular effect, often intuitively, without knowing exactly what they're doing. A note that occurs twice, let's say on an upward run and then on a downward run, might come out frationally different in those two positions in the melody when sung naturally, but auto-tuning will remove that subtlety.

If you're worried about your own pitch, practise against recordings or instruments; record yourself and listen back to it; or just sing unaccompanied and really listen as you sing - but don't for heaven's sake just give up and sing badly and lazily with the idea of correcting it electronically. If you do that, you'll just be on a downward spiral and find it ever more difficult to get it right on pitch.
