me and my friend were trying to play along with seek and destroy, with our strings both in tune using two separate tuners, and the notes in seek and destroy had a higher pitch, and me and my friend looked at each other and said 'they sped this shit up'
either that or they all just tuned their instruments to each other before recording it to a note that didn't exist, or maybe me and him staying up for a few days had something to do with it, i don't know, but after learning to play the guitar and realizing that dave mustaine was far more talented as a musician than every member of metallica combined, i didnt really respect metallica that much anymore, and them speeding up their songs sounds like something they might have actually done
