The Belgian-Australian multi-instrumentalist told The Sunday Mail he thought the Glee cover of "Somebody That I Used To Know," performed by Darren Criss and guest star Matt Bomer, sounded like "it's playing to you from a cardboard box." 

Gotye (AKA Wally de Backer) blamed the botched rendition on the vocals, which he felt were "ultra-dry" and "sounded pretty tuned and the rock has no real sense." 

He did have something nice to say about the instrumentals: "They did such a faithful arrangement of the instrumentals," Gotye said, before adding, "but the vocals were that pop Glee style...It made it sound dinky and wrong."
