Grammy-winning rapper Kanye West is feeling some backlash this week after being announced as a performer at the upcoming Glastonbury music festival.

According to reports, a petition for Ye not to perform at Glastonbury has thousands of signatures as of Thursday (March 19).

Kanye West is all set to headline England’s Glastonbury Festival in June — but thousands of angry music fans are hoping that will change. By Wednesday afternoon, the petition had just over 50,000 signatures. (It should be noted that anybody — not just Glastonbury ticket holders — can sign.) (TIME)

The petition blasts Kanye and calls him out for musical injustice.

“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….he should listen to his own advice and pass his headline slot on to someone deserving! Lets prevent this musical injustice now!” (Change)

Ye’s involvement at the festival became public knowledge earlier in the week.

No stranger to backlash, Ye’s longtime pal Jay Z previously angered Glastonbury concertgoers.

In 2008, fans made a fuss about Jay Z headlining the festival — and Oasis frontman Noel Gallagher even got involved, saying, “I’m not having hip-hop at Glastonbury. It’s wrong.” But none of that stopped Jay from performing, so it’s unlikely that anything will keep Kanye from performing either. (TIME)
