Not as much as the Beatles or Led Zeppelin... I don't know what your thoughts are, I'm just putting it out there. You must be joking. If Cliff Burton-era Metallica can be called over-rated, than so can the Beatles and Zeppelin. I'll agree 90's and later Metallica is nothing special, but the first Metallica 3 records are as much masterpieces as any Zep or Beatles recordings. Uhh, sorry, but no. Nothing Metallica has ever done can compare to Revolver or Rubber Soul in the "masterpiece" category. For that matter, nothing they've done can compare to Sgt. Pepper, The White Album, Abbey Road... well if you need to be picky, I'd say that Master of Puppets is the best heavy metal record ever made. If you don't want to put it up with beatles stuff, fine, but it's definitely one of the best records ever made
