West was revealed as the Saturday night headliner at Glastonbury on Monday (16Mar15), prompting many festival regulars and others to protest the booking.

One person opposed to the idea of West performing at the event in June (15) launched a petition calling for organisers to rethink Kanye's top billing.

The move upset Stormzy, who appeared alongside West when he debuted new song All Day at the BRIT Awards last month (Feb15).

He tells NME.com, "Kanye headlining Glastonbury is a sick booking. He’s not your usual headliner but with everything that’s going on with him at the moment, this is the right time.

"Unless it’s going to be your Coldplays or your Arctic Monkeys, the headline slot is always going to be controversial. It’s a festival that has a lot of history and it’s more associated with a certain type of music, so anything that strays away from that is going to cause issues. A lot of people are stuck in the past.

"But if festivals don’t make changes now, when they try and do it later it’ll be more difficult. Kanye’s booking makes it easier for another rap, R&B or hip-hop act to headline Glastonbury in the future. It’ll be similar to the Jay Z thing back in 2008 - when it was announced, everyone was skeptical but when it happened, everyone thought it was sick. I think Kanye will be a proper popular show. A good show is a good show, good music is good music."

He adds, "People say they're unhappy about the booking because of Kanye's ego but rock stars of the stereotype that normally headline Glastonbury are probably the most egotistical people there are...

"I don’t think I’ll be on stage with him this time... I wouldn’t be surprised if he brought Paul MCCartney on stage. It would make a lot of sense. And everyone will forget all the s**t they were chatting before."
