LATEST: Rockers Metallica have hit back at accusations their new album features poor quality audio.
The new LP, Death Magnetic, has been a worldwide hit - scoring number ones in both the U.S. and the U.K.
But the record has been dogged by claims that the CD features tracks which are substandard to the versions on the Guitar Hero video game.
However, the band's co-manager Cliff Burnstein insists that the fans' reaction to the disc has been "overwhelmingly positive".
He tells the Wall Street Journal, "There's something exciting about the sound of this record that people are responding to."
