Metallica is bringing the heavy to Stranger Things 4.
The metal legends' classic song "Master of Puppets" is featured on a newly expanded version of the Netflix sci-fi series' season four soundtrack, which was released Friday to coincide with the premiere of the season's final two episodes.
Thanks to its inclusion in the new episodes, "Master of Puppets" was trending on Twitter Friday morning. If you haven't had time to watch yet, though, be careful before you search "Master of Puppets" on social media, for only spoilers will follow.
"Master of Puppets" joins the songs featured on the initial Stranger Things 4 soundtrack, which, of course, includes Kate Bush's resurgent hit "Running Up That Hill."
The full Stranger Things 4 soundtrack is available now via digital outlets. It will be released on CD and cassette September 9 and on vinyl November 4.
