Pick any 5 from Kill 'em all, Ride the Lightning, M.O.P...
As long as Cliff's solo (Anesthesia, Pulling Teeth) is one of them...
They went too commercial for me from And Justice for All (and on)... Remember, Im old and got Kill 'em All when it came out. (1983 when I was a H.S. Junior)...
My taste and opinion of them may be a bit different than most here.
