The Australian singer and multi-instrumentalist's track was featured on a the US TV show earlier this month, but he was less than impressed with the results.
He told Australia's The Sunday Mail newspaper: ''They did such a faithful arrangement of the instrumentals but the vocals were that pop 'Glee' style, ultra-dry, sounded pretty tuned and The Rock has no real sense, like it's playing to you from a cardboard box.''
In another interview, the musician - real name Wally de Backer - said: ''It made it sound dinky and wrong.''
'Somebody That I Used to Know' has been a huge hit worldwide, topping the charts in 17 countries, and the musician admitted he finds the success of the track - which he recorded in a home studio on a tiny budget - is ''surreal.''
He added: ''I wrote the song and everything else has been a series of surprises
''In a way, after you've made a record, you've made it and everything else that happens feels like you are a bystander. It is kind of surreal.''
