i have no problem w/AutoTune (nor Melodyne) - IF its used as a make-up. precise and careful editing, etc. tbh, i love it. i love it on vocals, bass, strings, whatever. sometimes for 'creative correction', build up harmonies, etc.
but i hate the "T-Pain" (Cher?, Eiffel65?, tons of others..) settings.
i try to avoid of listening those productions - but damn, i hear them everywhere.
the "T-Pain" effect is overused, it is boring, its not funny, it makes everybody 'sing' the same. and the icing on the cake is the iPhone version. damn, maybe just i lost my sense of humour?
you can hate me now
(PS: i find Looney Island's "I'm On a Boat" funny.
