It's such a rarity for someone to understand what auto tuning is! All the major music artists and aspiring music artists use auto tune. Even Adele is auto tuned. When people think of auto tune, they think of the "T-Pain" voice. Auto tune is a wide range of things. It reduces human error. No one is going to be able to sing a song in the right key and pitch 100% of the time. No one. Auto tune merely corrects the human error. As for vocal talent, Katy Perry is low on the talent.. She gets off pitch way too easily. She's one of those artists that made it with looks and very little talent. ALL, yes I said ALL of her music is heavily processed. GaGa is flipping weird. However, she does have the talent. I am going to stop now because I can ramble on and on about this stuff lol.
