 9.19.19  12:04 am   I think It could be useful to use in the future, just to smooth out the edge a bit on vocals. And I'm not talking about the 100% wetness, T Pain style autotune. You may only need 5% of it or even less.  But then again, it's all up to you.
i used to use it lightly on the backing harmonies, and then one day i decided to stop, and it sounded perfectly in tune. and slightly more genuine, and of course the bragging rights are top notch. also good practice
