[Master of Puppets] Metallica CDs $4

[Will Collier]

I was a record store flunkie when that album came out. Everybody in the store loved it, but the boss advised us to not play it when "older customers" were on the floor. "It's just too extreme."

That sucker went gold with zero radio airplay and no videos (and of course no streaming). One of the great word-of-mouth records of all time.
