America’s “President of Hip Hop” has some British knickers in a bunch. Some diehard fans of the U.K.’s famous Glastonbury music festival are upset that the headliner of the show this year is rapper Jay-Z.

This is the first time an Urban music artist has been selected as the main act of the show, a sign to many festival-goers that the event is straying from its Rock and Roll roots.

Some are even blaming Jay-Z for the last 200 tickets (out of tens of thousands) not being yet sold.  Even Trip-Hop artist Tricky (Yes, Lynn’s music partner and boyfriend on the TV show “Girlfriends” has chimed in. In an interview on Friday with the U.K.’s  National Post, he said “I can understand in some ways, because an American artist headlining Glastonbury is probably a bit weird for people. And the fact that it’s an urban artist - and he’s not actually that good. If it was like, Public Enemy or Rakim, you might get away with it, because Rakim’s an extreme talent, and Public Enemy changed the face of music. People in England would probably relate to that more. But the ‘Bling-bling, I’m God’ sort of bulls—, English people ain’t into that.

Jay-Z, on the other hand, has no shortage of supporters, including several English artists like neo-soul sensation Estelle and others. “

“I’ve never ever had a show that’s caused this much stir so I’m really looking forward to it,” says Jay-Z. “I know we don’t all play guitars but we all have to respect each other’s music.It’s beautiful that people feel passionate about an event, you have to have an opinion about who should perform there, but the world changes and we have to embrace the change.”

Oasis rocker Noel Gallagher slammed the booking of Jay-Z shortly after tickets went on sale.

"If it ain't broke don't fix it," said Gallagher, whose band headlined Glastonbury in 1995 and 2004, criticising the decision to book a hip-hop artist at a festival traditionally dominated by guitar and dance music.

"If you start to break it then people aren't going to go. I'm sorry, but Jay-Z? No chance. I'm not having hip-hop at Glastonbury. It's wrong."
