Metallica have leaked a ten second clip of a song from their highly anticipated new album online.

It's not clear which track is featured in the clip, although fans are already speculating on the band's fansites.

'Death Magnetic', Metallica's follow-up to 2002's 'St Anger', is released worldwide on September 12th.

As previously reported, as well as traditional formats, the album will also be released simultaneously on the next edition of Guitar Hero.

The band will play two club shows in Berlin and London this September in support of the release.
