*Apparently there’s a right and wrong way to use Auto-Tune, and according to the man who ran it into the ground, Kanye West is using it the wrong way.

“There are a lot of guys that use Auto-Tune that cannot sing,” T-Pain tells the Huffington Post in a new video interview. “Kanye uses it, but he doesn’t use it correctly.”

T-Pain said West still “makes great music with it,” but his issue is that Yeezy sings first and Auto-Tunes later. “You don’t know how it’s going to come out. You can’t catch your mistakes before they happen. So sometimes it gets a little wobbly and things like that.”

T-Pain gives his stamp of approval to Kanye’s 2008 album “808s & Heartbreak,” because he “had a lot to do with that album.”
