Kelly Clarkson may have her own catalog of amazing tracks, but the vocalist is also known to bust out a cover song or two during her live performances. In 2012 alone, Ms. Clarkson has been taking requests (have you ever heard of any other pop superstar doing this? Clarkson is all about the fans!) while on her tour in support of her 'Stronger' album. So, out of the five covers we've selected, which tune do you think Clarkson killed it on?

In January 2012, after the passing of legendary blues singer Etta James, Clarkson paid tribute to the 'At Last' songstress by performing 'I'd Rather Go Blind' live at Radio City. It was a beautiful and powerful homage to the late great James -- there are few others who can really do that song justice like Ms. Kelly. Then, in February 2012, the Texan took on Demi Lovato's 'Skyscraper' while performing in Orlando, which must've been a surreal moment for the young Lovato once she saw Clarkson's rendition.

One month after she covered 'Skyscraper,' Clarkson treated fans to another live cover tune, this time belting out Paramore's ballad 'The Only Exception' in Indiana. While her tone and style differs from that of Paramore frontwoman Hayley Williams, Clarkson made the song her own and once again wowed us with her talent. Soon after, during a gig in L.A., Clarkson gave fans a double dose of cover songs. The 'Mr. Know It All' hitmaker sang Britney Spears' 'Till the World Ends' and also gave concert goers chills as she hit all the right notes on 'When You Believe' by Mariah Carey and Whitney Houston.
