Although Beck doesn't seem too upset about Kanye West's antics at Sunday's Grammy Awards, Garbage lead singer Shirley Manson has some choice words for the hip-hop star.

"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," Manson said Monday in a Facebook post. "Grow up and stop throwing your toys around."

West made headlines Sunday night when he went on stage as Beck accepted the Grammy for Album of the Year. During E!'s post-Grammys coverage, West said, "If they want real artists to come back, they need to quit playin' with us. ... Beck needs to respect artistry, and he should've given his award to Beyonce."

Beck, for the record, told Us Weekly that he was excited when West joined him.

"He deserves to be on stage as much as anybody. How many great records has he put out in the last five years, right?" said Beck, who agreed that Beyonce should have won the award.
