I said it once and I'll say it again: auto-tune can be used in an artistic way. A few artists that don't need it use it for artistic reasons.
Examples:
Bon Iver singing normally:

Bon Iver using auto-tune:

(it's about halfway into the song)
Autotune isn't just for making bad singers sound good.
Quote:
I'm sorry, but I just do not have that much respect for any artist who completely auto-tunes their voice. If you can't produce a sound worth listening to, then why are you producing any sound? I just don't see how anyone can take these people seriously when they can't even sing.
