Eminem is the latest musician to receive harsh criticism for lip-syncing a performance.

The Detroit emcee performed two singles, “Berzerk” and “Survival”, on Saturday Night Live last weekend. But the Em is accused of lip-syncing his performance of “Berzerk.”

A rep for the rap icon told TMZ that he didn’t lip-sync but used the “vocal track underneath his live vocals.”

“He just likes this sound and if you listen to his albums they are done the same way,” the rep said.

Technically that’s not lip-syncing but more like voice assist. It still take away something from a live performance.
