T-Pain might have put Auto-Tune on the map for the pop, R&B, and rap audience in the early 2000s, and artists since may have butchered it, but plenty of stars were using it way before him. One you may not even be aware of? Cher, who was the first person to use Auto-Tune on a big pop hit—1998’s “Believe.”

Kanye West, who has made creative use of the software in his music, is a person that is thankful for this. After a fan asked Cher on Twitter about meeting Kim Kardashian during the Met Gala, the pop goddess revealed that Kanye thanked her for Auto-Tune. See the tweet below.
