Not everyone is happy that Kayne West is set to headline the 2015 Glastonbury Festival.

On Monday (March 16), festival organizer Emily Eavis tweeted that the "All Day" rapper would perform on the Pyramid stage at festival's Saturday night event. Her tweet was met with both positive and negative comments and — to everyone's surprise — an actual petition to get his performance canceled.

Titled "Cancel Kanye West's headline slot and get a rock band," the petition began to circulate not soon after Eavis made the announcement. It reads: "Kanye West is an insult to music fans all over the world. We spend hundreds of pounds to attend glasto, and by doing so, expect a certain level of entertainment.

"Kanye has been very outspoken on his views on music," the document continues. "He should listen to his own advice and pass his headline slot on to someone deserving! Lets prevent this musical injustice now!"

The petition was started by Neil Lonsdale, a first-time Glastonbury attendee, who tells the BBC that Glastonbury should be about "guitar music" and that the hip-hop star's name on the bill is "a waste of a headline slot."

The NME reports the petition already has 21,000 signatures, which is just a drop in the bucket compared with the estimated 135,000 people who attend Glastonbury each year.

The Foo Fighters and Lionel Richie are slated to headline the first night of the festival, which takes place June 24 to 28 in southwest England. The festival is already sold out.
