^ best example of autotune vocals ....

Simple:
You are not a talented if you have auto-tune in every song on every word, I do not care if its famous, if its the new evolution of music, I do not care how successful it is, its just not talented.

that means either they can't sing or they just want to sound tech-y or sound like a robot

I compare auto-tune abuse to that of the guitar solo abuse in 70's and 80's rock. It will get old eventually.

though still people are obsessed with that
