Taika Waititi basically gambled the entire vibe of a multi-million dollar franchise on a single scream. You know the one. That high-pitched, primal Robert Plant wail that kicks off "Immigrant Song." When we talk about the song in Thor Ragnarok, we aren't just talking about a cool needle drop. We are talking about the moment Marvel Studios finally stopped taking itself so seriously and embraced the cosmic absurdity of its own source material.
Honestly, before 2017, Thor was kind of a drag. The first movie was a Shakespearean family drama with some bleached eyebrows. The second was a gloomy trudge through "The Dark World" that most fans have conveniently scrubbed from their memory. Then Waititi showed up with a briefcase full of 80s synth-pop aesthetics and a relentless obsession with Led Zeppelin. It worked. It worked so well that it redefined how Disney handles its soundtracks, moving away from generic orchestral swells toward iconic rock anthems that actually mean something to the plot.
The Story Behind Using Immigrant Song in Thor Ragnarok
Securing a Led Zeppelin track isn't like licensed pop music. It’s a nightmare. The band is notoriously protective of their catalog. They famously turned down Richard Linklater for School of Rock until Jack Black filmed a literal plea to the "Gods of Rock." So, how did a superhero movie get the green light?
Waititi used the track in his initial pitch sizzle reel to Marvel executives. He knew the lyrics—referencing the "hammer of the gods" and "Valhalla"—were a literal blueprint for Thor’s Norse mythology. But the band didn't say yes immediately. It took seeing the finished cut, or at least a very polished version of the bridge battle, for the legends to realize that "Immigrant Song" wasn't just background noise. It was the heartbeat of the character's evolution.

The song appears twice. First, in the opening scrap with Surtur. It’s funny, fast, and light. But the second time? That’s the peak. On the Bifrost bridge, as Thor realizes he doesn't need Mjolnir to be the God of Thunder, the lightning strikes right as the riff drops. It’s pure cinema. It told the audience: The old Thor is dead. This guy is a rockstar.
Why the Lyrics Actually Matter (For Once)
Most movie soundtracks just pick a song that sounds "cool" or "tough." Look at the Suicide Squad (2016) soundtrack—it was basically a Spotify "Top Hits" shuffle. But the song in Thor Ragnarok is different because it’s a narrative mirror.
Robert Plant wrote those lyrics in 1970 after a tour in Iceland. He was obsessed with the idea of Viking explorers coming from the "land of the ice and snow." When Thor lands on the bridge to save his people, he is quite literally an immigrant leading a group of refugees. He is leaving his home (which is currently exploding) to find a new one. "We come from the land of the ice and snow, from the midnight sun where the hot springs flow." It’s Asgard. It’s literal.

Beyond Zeppelin: The Synth-Wave Sound of Mark Mothersbaugh
If "Immigrant Song" is the soul of the movie, the score by Mark Mothersbaugh is its nervous system. You might know him from DEVO. Yeah, the "Whip It" guys.
Waititi didn't want the standard Hans Zimmer-style wall of horns. He wanted something that felt like a tattered 1970s comic book found in a garage. Mothersbaugh used vintage synthesizers—specifically the MiniMoog—to create a soundscape that felt alien and retro-futuristic. This is most obvious in the track "Grandmaster’s Jam Session." It’s weird. It’s quirky. It’s exactly what Sakaar should sound like.
- The Surtur Fight: High energy, heavy drums, sets the tone that this isn't your dad’s Thor.
- The Scavenger Fight: Weird, off-beat percussion that introduces the chaos of Sakaar.
- Pure Imagination: Did you catch that? When Thor is being introduced to the Grandmaster, a warped, creepy version of the Willy Wonka song plays. It tells you everything you need to know about Jeff Goldblum’s character without a single line of dialogue.
The "Guardians" Effect and the Future of MCU Music
A lot of people credit James Gunn for fixing Marvel's "boring music" problem with Guardians of the Galaxy. That’s fair. But Gunn uses music as a tether to Earth—Peter Quill’s connection to his mom. Waititi used the song in Thor Ragnarok to do the opposite. He used it to blast us further into the cosmos.

Since Ragnarok, we’ve seen a massive shift. Black Panther leaned into Kendrick Lamar. Captain Marvel went full 90s grunge. Even Thor: Love and Thunder tried to double down by using four different Guns N' Roses tracks. Some say it was overkill, and maybe it was. "Sweet Child O' Mine" is great, but it didn't have the "holy crap" factor that "Immigrant Song" had. You can't just catch lightning in a bottle twice by throwing more leather jackets at the screen.
The genius of the Ragnarok needle drop was the restraint. They waited. They teased it. And then they let it rip.
Practical Takeaways for the Super-Fan
If you're looking to dive deeper into the audio world of Asgard, don't just stop at the movie's theatrical release. There’s a lot of texture you might have missed if you were just watching the explosions.
- Listen to the "Immigrant Song" (Live) versions. If you want to feel the energy Waititi was aiming for, check out Led Zeppelin’s How the West Was Won live album. It’s faster, meaner, and matches the Bifrost battle’s tempo better than the studio version.
- Track the Synth motifs. Watch the movie again and pay attention to the music whenever Loki is on screen. Mothersbaugh gives him these slippery, gliding synth notes that represent his shifty nature. It’s subtle brilliance.
- Compare to the "Love and Thunder" soundtrack. Notice the difference. In Ragnarok, the music feels earned. In the sequel, it feels like a mandate. It’s a masterclass in how "more" isn't always "better" when it comes to licensing classic rock.
The song in Thor Ragnarok wasn't just a marketing gimmick to sell tickets. It was a declaration of independence from the "boring" Marvel formula. It proved that these movies could be bright, loud, and incredibly fun without losing their emotional stakes.
To really appreciate what happened here, go back and watch the bridge scene one more time. Turn the volume up way past what your neighbors would prefer. When Robert Plant screams as Thor descends with lightning leaking out of his eyeballs, you’re not just watching a movie. You’re witnessing the exact moment the superhero genre realized it was allowed to have a soul. That energy is why, nearly a decade later, we’re still talking about a 50-year-old rock song in a movie about a space Viking.
