Jay-Z headlined the Glastonbury festival this year and kicked off his set with a cover of Oasis' "Wonderwall."

It was a great idea and a jab at Noel Gallagher who was critical of the decision to have Jay-Z at the fest. However, while he may be the king of rap, it proved he's not good at singing on key.

It goes into "99 Problems," which offered a bit of AC/DC thrown into the mix.
