As I commented elsewhere, Beyonce is clearly using autotune. The best way to tell the difference is to just become familiar with singers that predate autotune. It's the way they abruptly (too quickly) shift notes, and then stay dead on the note. You'll hear it after a while, and then you can't unhear it. It's a one-way ticket.

So true. But so is Karen Carpenter, Julie Andrews, Grace Slick, etc., that all predate autotune. I suspect a cause and effect there.
