10. Sonic Boom (Sonic CD)
Sonic Boom was the first vocal song in the Sonic franchise. Performed by Pastiche, this is a very catchy and memorable song. It's a simple song about overcoming obstacles and saving the world. There is also a version by Crush 40 which is alot heavier, but no less memorable.
9. E.G.G.M.A.N (Sonic Adventure 2)
This is about as simple as a song can get, lyrically. Performed by Paul Shortino, it's a song sung from Dr. Eggman's point of view. To put it simply, it's a song about Eggman wanting to destroy Sonic and take over the world. What really makes this track memorable is the opening riff. When you hear it, you know trouble is coming.
8. Green Hill Zone (Sonic the Hedgehog)
I might as well include one song from the Genisis era. Green hill zone is classic sonic, and it's about as classic as you can get. This song is fast paced, yet surprisingly relaxing. It's a track that lets you know that adventure awaits, and is a joy to listen to.
7. Perfect Dark Gaia - Phase 2 (Sonic Unleashed)
The final boss themes of the modern Sonic games have all been orchestral renditions of the main themes, and this is the best one by far. A rendition of Jared Reddicks "Endless Possibility", this song is epic. It's hard to describe the emotions that this song makes you feel. Courageous, empowered, excited and ready to save the world. This song just might make those 20 minute werehog stages worth it.
6. His World (Sonic the Hedgehog)
Ali Tabatabaee & Matty Lewis
His world is a fantastic song. One-third rock, one-third rap and one-third orchestral, the song basically says "This is Sonic. Do not mess with him. He's the best." The song is performed by Ali Tabatabaee & Matty Lewis of Zebrahead. There are many different versions of this song. My personal favorite is the full Zebrahead version. Sonic '06 was a bad game, but this song is among the best.
5. Escape from the City (Sonic Adventure 2)
Ted Poley & Tony Harnell
If you've played Sonic Adventure 2 even once, you already know all the words to this song. In fact, it's probably stuck in you're head now. This is without a doubt the catchiest song in the entire franchise. Performed by Ted Poley and Tony Harnell, this song is a great way to start a great game. Also, it has a pretty sweet bass line.
Live & Learn (Sonic Adventure 2)
If City Escape is a great way to start Sonic Adventure 2, then Live & Learn is the perfect way to end it. Crush 40's second song for Sonic is amazing. It is argueably the most popular vocal song in the Sonic franchise. If you are reading this list, then you've probably already heard it. However, I believe this song is slightly overrated, which is why it's only number 4.
3. Knight of the Wind (Sonic & The Black Knight)
Although this choice may be a little surprising, I believe that Knight of the Wind is one of the greatest Crush 40 songs of all time. Awesome lyrics, great music and one of the greatest guitar solos I've ever heard. Knight of the wind is a great track.
2. What I'm Made Of... (Sonic Heroes)
This song is better then Live & Learn. Although Sonic Heroes is nowhere near as good as the Adventure titles, the final boss theme is fantastic. Great opening riff, cool chords and a solo that's even better then Knight of the Wind. However, there is still one song that can top it.
1. Open Your Heart (Sonic Adventure)
Crush 40's first Sonic song, and also their finest. This song has everything. Awesome guitar, awesome lyrics, awesome vocals and even an awesome drum track. It also has one of the best messages of any Crush 40 track. No matter what happens, no matter how great the evil against you is, you will not lose. Can't hold on much longer, but never letting go. That's what heroes are for. This song is perfect.
