One of the most beloved parts of the Sonic the Hedgehog franchise is not only its characters, gameplay, or nostalgia, but its music. Sega's popular game series, while sometimes criticized for its gameplay or writing, has yet to truly disappoint when it comes to its soundtracks. Bands such as Crush 40, Cash Cash, and Zebrahead have all contributed to Sonic's iconic rock-genre of music, creating some of the most memorable character themes and boss battles of the entire franchise.

The Sonic series has some amazing instrumental soundtracks, but many of its best songs have lyrics to accompany the game's story.

Overall, the music throughout the Sonic franchise stands out as some of the best elements in any Sonic game.

While searching for three emerald shards across the Halloween-themed level, Hunnid-P can be heard rapping about Knuckles and his adventures in the fan-favorite song "A Ghost's Pumpkin Soup."

The song, sung from the perspective of Knuckles himself, is as catchy as it is unique.

"Open Your Heart" details the events of Sonic Adventure, specifically the creature Chaos and the threat he poses to the Sonic universe. It even touches on the story elements of the game, such as Chaos' hatred and rage. It hints at Sonic's true mission to bring peace to Chaos, as opposed to simply sealing him away, and foreshadows the game's climax.

All of Me" by Crush 40 perfectly captures the game's tone and accompanies the climactic boss fight against Devil Doom during the game's finale.

As Shadow slowly learns about his past and his purpose, his disjointed memories cause him no end of grief. The song touches on these emotions and reveals some of Shadow's frustration and anger throughout the game.

In Sonic Colors, Sonic and Tails explore an interstellar amusement park and befriend colorful alien creatures known as Whisps. The lyrics for "Reach for the Stars" are written from Sonic's perspective and tie in thematically to the game's adventure, touching on its outer-space setting and emphasis on color as a game mechanic.

If there's one good thing to come from Sonic '06 besides nostalgia, it's the soundtrack. First heard in the end credits of the game, "His World" is both the theme of the game and of Sonic himself. The original version was written and performed by Zebrahead, while Crush 40 eventually made another popular cover, both of which were reprised in various Sonic sequels.

"His World" is all about Sonic and his heroic personality. It fits well within the context of its original game, Sonic '06, but also within the franchise as a whole. It's a perfect character theme for Sega's famous mascot, embodying Sonic with its rock and roll music and thematic lyrics.

The original song was composed by Spencer Nilsen and performed by Pastiche, with eventual remixes performed by both Crush 40 and Cash Cash. It embodies the electronic rock genre of the early 90s, yet is still considered a fantastic song by modern day Sonic fans.

"Sonic Boom" plays twice during Sonic CD, once during the intro and once during the ending. Its lyrics are simple and straightforward, but set the tone well for the game as a whole. The lyrics speak directly to Sonic, encouraging him and reminding him of his heroic goals throughout his adventure.

1 "Gotta Go Fast" Might Be Sonic's Most Famous Song

Perhaps almost as famous as Sonic himself is his catchphrase, "gotta go fast," which originated from the Sonic X series' opening theme song, "Gotta Go Fast." The anime was first broadcast in Japan in 2003, with a localization by 4Kids Entertainment available later that year. "Gotta Go Fast" was the opening theme of the American dub, becoming popular for its upbeat tempo and recognizable lyrics.

While the song was fairly straightforward, "Gotta Go Fast" became nostalgic for Sonic fans who grew up watching Sonic X. With a catchy beat, simple lyrics, and an energetic tempo, the song wasn't only a great theme for a kid's show, but a classic soundtrack loved by Sonic fans to this day.
