Ne-Yo, STFU because you've worked with Rihanna's stinking ass, who uses auto tune to the fullest, in all of her songs and on top of that, she can't even sing! The people who use auto tune in this business who can't sing worth a damn are

Rihanna
Katy Perry
Britney Spears
Kesha
Fergie
Justin Beiber
Lady Gaga
T-Pain
JLO

and a bunch of other "singers."

He has a point, but how dare he say this when he's worked with someone who uses autotune to fix his/her vocals.
