METALLICA was scheduled to fill up your iPod on March 31 with their entire discography. The iTunes date for the "digital box set" is now April 14th.

A previous Metallica update on the box set reads: "What exactly does 'entire catalog mean?' you ask ... that would be 163 tracks including all the studio albums from Kill 'Em All up through Death Magnetic, S&M, Some Kind Of Monster, the two tracks from Live From Live Earth, and 'I Disappear' from the Mission Impossible 2 soundtrack. Our little set here also includes the live tracks that were released as part of the album versions on iTunes: 'The Four Horsemen', 'Whiplash', 'For Whom The Bell Tolls', 'Creeping Death', 'Battery', 'The Thing That Should Not Be', 'One' and '...And Justice For All'."
