In my opinion, this app kills the art of rap. It is promoting minimal effort in making music, and giving false encouragement to people that the cheesy/auto tuned noise produced is a something worth sharing. It is a cool idea, but the auto tuning is very outdated.
Also, you can only try it one time before paying for it. They do offer a free 7 day trial, but it does not advertise anywhere that you can cancel the subscription after 7 days. I was almost suckered into it. Watch out!
