Yeah one is good but Master of Puppets I prefer. I'd say:
Master of Puppets
Sanitarium
Disposable Heroes
Ride The lightning
Unforgiven
Seek and Destroy
Fade to black
Nothing Else Matters....
....Are all on a par or better, I love all the unsung atmospheric album track gems as well, like trapped under ice, Dyers Eve, My Friend of Misery, Metal Melitia, all of them, I don't give a fuck what people say the Black album is clearly awesome, they lost something from Load onwards, too self-conscious maybe. Like someone said Creeping Death is a contender as well!
