Best Heavy Metal Band of all time. (Do people still listen to metal?)

So, Metallica has fallen, and can't get album sales up.

What I don't understand is, many people pick on the Black Album, it was good at the time, and still the best selling.

The Load (of garbage) album was when Metallica became a parody for metal. Not sure why Jason hung around when that was released, but Reload sent him packing. At least he did two good albums.

Kill 'Em All U.S. Sales 4.5 million
Ride the Lightning 6.9 million
Master of Puppets 7.9 million
Post Cliff albums.....
...And Justice for All 9.7 million
Metallica 17.3 million
Load 5.4 million
Reload 4.4 million Last album with Jason Newsted?
St. Anger 2 million
Death Magnetic 2.1 million
Hardwired... to Self-Destruct 1.2 million
72 Seasons 373,000
Can't live off of Social Security 56,000 (Rumored to be released in 2030)
