Master Of Puppets was OK not my favorite though. Dave Mustaine and Megadeth own Metallica as far as thrash. Powerslave goes 3rd in my Maiden line up with Number of the Beast being second.
AC/DC peaked with Back in Black and the follow up For Those About to Rock. Both were solid albums definitely, but they declined so fast after that by making albums with 1 solid song and the rest garbage. Who Made Who was their last album I bought.
Queen has a few songs i like but never bought their music either.
