Jukebox Hits: '80s Metal

The fist-pumping nature of these tunes shouldn't overshadow how absolutely vital they are to the evolution of heavy metal; just listen to Sepultura's thrashed-out vision of doomsday or Suicidal Tendencies' trendsetting hardcore. Hitting the mainstream is evolutionary too, so don't forget to salute Skid Row's monster MTV hits, Dio's riff-happy hobgoblin and Ozzy's bark in the night.
