Metallica recently hit TikTok for a special version of "Master of Puppets."
The band did a duet with "Stranger Things" actor Eddie Munson, playing along with the now-famous scene from the season finale.
The band even wore Hellfire Club t-shirts, just like the ones worn in the Netflix series.
The caption read, "Eddie, this is for you!"
Meanwhile, there's a video of Joseph Quinn who plays Eddie that's going viral because 'practice makes perfect.'
