Jay-Z has defended the decision to book him to headline Glastonbury Festival when speaking to Tim Westwood. Appearing on 'Radio 1' he said he couldnt understand the furore: It's ridiculous, if we don't embrace what is new, then how do we progress?" Jigga continued: "It's 2008, what is that about? That's such old school thinking, that's not even how the world thinks anymore. So I was really taken aback." The legendary rapper headlines the Somerset festival this Saturday and were certain his show will be a highlight of the weekend. Getting philosophical Hova also told the radio station: "These barriers that they have are only put up there to separate us- They are there so people have a way of filing the music but that's not the way kids today listen to music. Good point Jay!
