The Napster situation was ridiculous for two reasons:
1) It led the RIAA going after everyone one and his mom for theft. Broke students and people downloading here and there shouldn't be arrested and booked by the FBI over the situation, nor should the be taken to civil court for thousands in damages. Large-scale offenders fine, but not John Q Citizen just grabbing a few tracks.
2) It wasn't even affecting album sales. Despite the fact that the costs of producing CDs, warehousing, shipping, etc had dropped and dropped CDs were still being released at $14.99 and up, and yet fans were still buying albums.
Metallica was already on the downhill slide musically at that point anyway. Progress is fine, but after the Black Album they had fewer and fewer quality songs on each follow-up. How Revolver gave Death Magnetic Album of the Year I will never know, but they were also still praising what's-her-face from In This Moment as one of the hottest chicks in metal despite the garbage that was their second album so what else should I expect?
Of "The Big Four," Metallica is without question in last place in terms of what they put out these days.
