I think Jody points to a great way to use pitch correction tools! Use it to get your melody right, then put that track in your ear while rerecording the vocal track. Like useing it as a melody support tool. That way you get the best from both worlds, end up a better singer, and get the optimal natural sounding result. In Melodyne, you can bounce the corrected track as midi, and put a vsti piano or another instrument, on, to sing to, and even use it to sweeten up the arrangement.

Hard pitch correction is for more commercial mainstream genres, and for studio's who can't get the singer back to re-record In Americana you need things to sound like if they were NOT pitch corrected, as that would sound like it is not "authentic". Yet, you need to get a great vocal track, so that's the way to do it.
