Query: SAD BUT TRUE: Metallica is DEAD! --- REST IN SELLING OUT

What is this? What do they think they are? Is this really the same Metallica, who created the greatest metal masterpieces - Kill 'em all, Ride the lightning, and MASTER OF PUPPETS ? My last advice to them. - Please retire right now, before it's too late.
