Loutallica is STILL p!ssed off about it. Hee Hee!
Lars might be mad about it but James Hetfield blamed it on voters who didn't have a clue about what metal was. Aqualung was a monster album and it probably did deserve a Grammy, just not one in that category. In the long run Metallica became the number 1 metal band in the world and eventually got their Grammy. They still sell out arenas worldwide, which probably helps to ease the sting.
