Ask any Sonic fan about the peak of early 2000s gaming music, and they won’t just say "Crush 40." They’ll hum that opening riff. You know the one—the high-octane, slightly gritty, and intensely aggressive guitar work of Jun Senoue. Honestly, while "Live & Learn" gets the mainstream glory, "What I'm Made Of..." is the dark horse that keeps people debating in Reddit threads twenty years later. It’s the song that defined the final showdown of Sonic Heroes (2003), but the lyrics aren't just about a fast blue hedgehog hitting a robot.
There’s a tension in the lines. A weird, identity-crisis energy.
Johnny Gioeli, the powerhouse vocalist of Crush 40, has gone on record saying this is his favorite track to perform. You can hear why. The vocals are raw. It’s not a "happy-go-lucky" team-up song. It’s a song about proving existence, and depending on who you ask, the lyrics belong to Sonic or his mechanical doppelgänger, Metal Sonic.
The Identity Crisis in What I m Made Of Crush 40 Lyrics
Most people assume the hero gets the theme song. In the Adventure games, that was the rule. But Sonic Heroes changed the vibe. When you reach the "Final Fortress" and face off against Metal Overlord—a Kaiju-sized, dragon-like version of Metal Sonic—this track kicks in.
Let’s look at the chorus:
"Try to reach inside of me, try to drain my energy... Let me show you just what I'm made of!"

If you’re playing as Team Sonic, this sounds like a challenge. You've got the Chaos Emeralds, you're going Super, and you're telling the villain to give it his best shot. But look at it from Metal Sonic's side for a second. The dude spent the entire game "reaching inside" others by copying their data. He’s a machine trying to find a soul. When he screams "Let me show you just what I'm made of," it feels less like a hero’s boast and more like a monster trying to prove he’s more than just nuts and bolts.
The line "Like a million faces, I’ve recognized them all" is another head-scratcher. Fans have argued this refers to Metal Sonic scanning every hero and villain in the series. He doesn't see people; he sees data points. One by one, they become "a number as they fall." That’s cold.
Why the Production Style Changed Everything for Crush 40
Before this song, Crush 40 was known for "Open Your Heart" and "Live & Learn"—anthemic, melodic hard rock. "What I'm Made Of..." was a pivot. It’s faster. It’s "metal-lite." Jun Senoue used a more distorted, compressed guitar tone here that basically paved the way for the even darker Shadow the Hedgehog soundtrack a few years later.
Basically, if this song didn't exist, we probably wouldn't have gotten "I Am... All of Me."
The Lyrics in Context
- Verse 1: "I don't care what you're thinking as you turn to me." This mirrors the standoff. Both Sonic and Metal are mirroring each other's movements.
- The Bridge: "You can take another life-long try." This is arguably the most "Sonic" line in the whole piece. It’s that classic cocky attitude—telling the rival that no matter how many times they try, the result will be the same.
- The "S.A.M.E." Version: If you’ve played Sonic x Shadow Generations recently, you might have heard the updated version. It keeps the core lyrics but polishes the 2003 rough edges.
The "Mandela Effect" and Other Fan Theories
There is a weirdly common misconception that the song repeats the word "Heroes" in the background during the chorus. It doesn't. That’s just your brain trying to link it back to the game’s title. Johnny is actually hitting those high "Hey!" ad-libs that he’s famous for in the Hardline days.

Also, can we talk about the "black mark on the floor" line?
"One by one they've all become a black mark on the floor."
In a franchise usually rated E for Everyone, that's a pretty grim way to describe defeating enemies. It suggests total erasure. Whether it’s Sonic destroying Eggman’s robots or Metal Sonic "deleting" his obstacles, it adds a layer of stakes that the bright, colorful levels of Seaside Hill didn't really prepare us for.
Why It Still Slaps in 2026
The reason this song stays in the rotation isn't just nostalgia. It’s the composition. The way the drum fill kicks in right before the second verse—Takeshi Taneda’s bass work here is actually insane if you isolate the tracks. It’s driving, relentless, and never lets up.
Most modern game music is cinematic and orchestral. It’s designed to stay in the background. But Crush 40 made music that fought for your attention. It’s loud. It’s distracting in the best way possible. It makes the boss fight feel like a high-stakes rock concert where the loser gets dismantled.

Actionable Insights for Fans and Musicians
If you're trying to cover this or just want to appreciate it more, pay attention to the syncopation in the chorus. The vocals land just slightly off the beat, which gives it that "push and pull" feeling.
For the lore nerds: Listen to the lyrics while watching the Sonic Heroes ending cutscene again. Specifically, watch Metal Sonic’s face when he reverts to his original form. He asks, "Why? I was built to be the one and only... why can't I defeat you?" The song is the answer. Sonic isn't "made of" data or mechanical parts. He’s made of something Metal Sonic can’t copy.
If you want to dive deeper into the Crush 40 discography, you should check out the "True Blue" or "Super Sonic Songs" compilations. They have the remastered versions where you can actually hear the vocal layers much better than the original GameCube/PS2 compressed audio files.
Check out the Sonic 30th Anniversary Symphony performance of this track too. Hearing a live orchestra try to keep up with Jun’s lead guitar really puts into perspective how fast this song actually is.
