OZZY OSBOURNE, MARIAH CAREY, and CELINE DION have been branded the "worst singers of all time".
The poll, carried out by British music 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." But the magazine's most scathing remarks are reserved for former BLACK SABBATH frontman Osbourne, who "now sings like he speaks - this may be a cause for sympathy but not for buying his albums".
YOKO ONO, LIMP BIZKIT star FRED DURST and "any death metal singer" were also among those criticised for their singing.
