Watch Kelly Clarkson Absolutely Nail Rihanna’s ‘Stay’ [VIDEO]

Kelly Clarkson is the most deserving of the title "American Idol". She can sing anything. And she proves it in concert when she covers Rihanna's "Stay".

The original still moves me, as it should. But Kelly's cover is definitely worth noting, especially since she's doing this live without a net. This was recorded on a cell phone at a concert in Pittsburgh. Even though its only cell phone audio, she sounds awesome.
