Did you see the Kanye West rant on E after the Grammys? He took over their air time to reprimand the Grammy association for giving the award to Beck instead of his favorite, Beyonce.

What happened free the Grammys didn’t exactly sit well within the American music community. Now musicians are starting to speak out against the rapper, who ridiculed Beck for winning album of the year instead of Beyonce. Garbage lead singer Shirley Manson weighed in by posting an open letter to Kanye, who she called a “complete tw*t,” on her Facebook page.

Read the full letter below:

Dear Kanye West,
It is YOU who is so busy disrespecting artistry.
You disrespect your own remarkable talents and more importantly you disrespect the talent, hard work and tenacity of all artists when you go so rudely and savagely after such an accomplished and humble artist like BECK.
You make yourself look small and petty and spoilt.
In attempting to reduce the importance of one great talent over another, you make a mockery of all musicians and music from every genre, including your own. Grow up and stop throwing your toys around. You are making yourself look like a complete twat.
Ps.I am pretty certain Beyonce doesn’t need you fighting any battles on her account. Seems like she’s got everything covered perfectly well on her own.
