I didn't really have any idea about some of these. Apparently Metallica went beyond the 1980s/1990s lifting a riff/stealing a lick thing and just did it for their whole career. Here is one I knew about. Excel/Tapping the Emotional Void has a drum and acoustic guitar part that is EXACTLY like Enter Sandman, Metallica's monster single off the Black Album (not suprising, cuz blacks steal things! el oh el) Excel was playing this in 1986, copyrighted it in 1988 and put it out on a 1989 record. Enter Sandman, 1991. You tell me how this isn't the typical 80s "Nice little piece of a song, lemme 'borrow' that from you." But this one, I can't believe I missed it off Death Magnetic. I didn't like the record that much, felt it was a bit boring and too long, but this, I can't believe I missed it. This is Metallica in 2008 totally stealing the beginning of Pearl Jam's "Why Go" single off that obscure little record, Ten. The rest of the song sounds very much like a distorted Ten album B-side. Thieving fucks. Some people say this isn't the same, but it totally sounds like it to me.
