I prefer no autotune at all, I don't mind a little autotune though, but too much of it is annoying and sounds unattractive, even more so when the artist has no vocal talent in the first place or isn't using any vocal talent on the track.
Pitch correction programs and autotune should all be banned, then we'll see who's making real music.
If you need autotune to appreciate music then you have no taste at all, of course IMO.
Pretty much every radio artist uses autotune, even country singers....and they have been for a long time. No one even knew about it until Cher messed with autotune's settings for "Believe".
Without autotune....the music world would be VERY different.
I have no problem with autotune making a track sound more perfect for repeat listening as long as the artist can duplicate it reasonably well LIVE. If they can't then
I really think its use as a special effect is going to reach its peak soon though, since everything gets old eventually...
