For those about to rock, best not to take any cues from Celine Dion.
The Canadian chanteuse's easy-listening rendition of AC/DC's "You Shook Me All Night Long" earned the otherwise lauded balladeer the ignominious honor of being voted the worst cover song of all time by a panel of experts at Total Guitar magazine.
While she only sang the apparently appalling tune once, a whopping six years ago, it was seemingly one time too many for the mag's connoisseurs.
"Cover versions have never been bigger but the number one worst song—Celine Dion covering AC/DC—is sacrilege," grouses Total Guitar editor Stephen Lawson.
Dion never released the track, dubbed an "offense" against music by the magazine, following her onstage duet with Anastacia during VH1's Divas Las Vegas concert in 2002. One-hit wonder Meredith "I'm a Bitch" Brooks accompanied the duo on guitar.
As Total Guitar is a U.K. publication, the remainder of the worst-of-the-worst roundup was unsurprisingly populated by British pop acts trying their hand at rock classics, including a Sugababes and Girls Aloud duet of "Walk This Way" and inaugural Pop Idol winner Will Young's version of "Light My Fire."
The magazine also released a best cover song roundup.
Jimi Hendrix's take on "All Along the Watchtower" came out on top, followed by the Beatles' "Twist and Shout," Guns N' Roses' "Live and Let Die" and Nirvana's "The Man Who Sold the World."
Tops the woman who deafened it every time.
