Ozzy Osbourne, Mariah Carey, and Celine Dion have been dubed the “worst singers of all time.”

The poll, administered by British magazine Q, lauds Elvis Presley as “the greatest voice of all time”, but singles out popular stars such as Dion and Carey for their vocal inability.

The judging panel says, “(Mariah Carey) may have an 100-octave range and the ability to sing so loudly that birds’ nests fall from tress, but that doesn’t make it right. (Celine Dion) grinds out every note as if bearing some grudge against the very notion of economy.”
