Open Your Heart

"Open Your Heart" is the main theme song of Sonic Adventure done by Crush 40. It is of a Hard Rock genre. Remixes have been made featuring Bentley Jones and K-Klub.

The song was composed by Jun Senoue, who also took lead guitar duties and had already been working as the head music director for Sonic and Sega related games for several years. In the early demo version of the song, Senoue even provided the vocals for the song. Eventually, Hardline frontman, Johnny Gioeli, was chosen as the lead vocalist, forming the group that would later become Crush 40. (They had not been officially named Crush 40 until years later.) Also involved in the song are Naoto Shibata on bass and Hirotsugu Homma on drums. The two later joined the Japanese bands, Loudness and Anthem.

Versions

 * Album Version - The version that appears on just about every CD release. Has an extended intro and ending that sounds like a thunder storm.
 * Game Version - The version that actually appears in Sonic Adventure. Basically the same as the Album version, but doesn't have the opening and closing storm sounds. It also has an extra vocal bit at the beginning of Johnny Gioeli yelling "Alright!"
 * Original Soundtrack Version - The version that appears on the Original Soundtrack (OST) 2CD set. It is the same as the version from the game, but has several of the extra vocal bits cut out.
 * Perfect Chaos Version - The version that is played during the first half of the final boss battle with Perfect Chaos. It contains the first verse then the chorus and then loops back to the first verse.
 * MJZ Remix - A laid-back remix that can be unlocked in Sonic Gems Collection.
 * Transmutor Vs. Razed In Black Remix - A fast paced and techno-based remix that appears on the Sonic Adventure REMIX album. Some have dubbed it the "Sonic Boom Remix" since the words "Sonic Boom" are said numerous times.
 * Chris Vrenna & Mark Blasques Remix - Another remix appearing on the Sonic Adventure REMIX album. This one stays more true to the original song vocal-wise (although it contains some original lyrics), while still adding a techno twist to it.

 * Demo Version - The original version of the song that features Jun Senoue as the lead vocalist.

Lyrics
thumb|300px|right|Open Your Heart Thunder, rain, and lightning

Danger, water rising

Clamor, sirens wailing

It's such a bad sign

Shadows of dark creatures

Steel clouds floating in the air

People run for shelter

What's gonna happen to us?

All the steps we take, all the moves we make, all the pain at stake

I see the chaos for everyone who are we, what can we do!

You and I are same in the way that we have our own styles that we won't change

Yours is filled with evil and mine is not

There is no way I can lose!

Can't hold on much longer - But I will never let go!

I know it's a one way track - Tell me now how long this'll last!

I'm not gonna think this way - Nor will I count on others!

Close my eyes and feel it burn - Now I see what I gotta do!

Open your ear, it's gonna be alright!

Ancient city blazing

Shadows keep attacking

Little children crying

Confusion, hopeless anger

I don't know what it can be but you drive me crazy

All your cunning tricks make me sick, you won't have it your own way!

Can't hold on much longer - But I will never let go!

I know it's a one way track - Tell me now how long this'll last!

I'm not gonna think this way - Nor will I count on others!

Close my eyes and feel it burn - Now I see what I gotta do!

Open your heart, and you will see!

(Guitar Solo)

If it won't stop, there will be no future for us

Its heart is tied down by all the hate, gotta set him free

I know it's a one way track - Tell me now how long this'll last!

Close my eyes and feel it burn - Now I see what I gotta do!

Gotta open your heart, dude!

Can't hold on much longer - But I will never let go!

I know it's a one way track - Tell me now how long this'll last!

I'm not gonna think this way - Nor will I count on others!

Close my eyes and feel it burn - Now I see what I gotta do!

''Open your heart, it's gonna be alright! (Yeah!)''

Open Your Heart!

Open Your Heart!

Yeahhhh...

Connection to Sonic Adventure
The lyrics to "Open Your Heart" are written from Sonic's point of view, and refer to many of the events and locations of Sonic Adventure.

The song mentions the destruction of the Knuckles Tribe in ancient times and the burning Emerald altar in the line "Ancient city blazing" and the appearance of the Egg Carrier is mentioned in the line "Steel clouds floating in the air."

There are multiple references to the final battle between Super Sonic and Perfect Chaos. For instance, Perfect Chaos' flooding of Station Square and the resulting panic this causes is mentioned in the song's first stanza:
 * Danger, water rising,
 * Clamor, sirens wailing,

Along with the last couplet that describes both the threat that Chaos poses and how it must be defeated:
 * If it won't stop there will be no future for us,
 * Its heart is tied down by all the hate, gotta set him free

The song's verse (and title) also references the same battle, particularly Sonic's tapping into the positive power of the Chaos Emeralds and transforming into Super Sonic:
 * Close my eyes and feel it burn - Now I see what I gotta do!
 * Open your heart, [...]

The song also contains references to Sonic's ongoing rivalry with Doctor Eggman in the lines:
 * You and I are same in the way that we have our own styles that we won't change,
 * Yours is filled with evil and mine is not
 * There is no way I can lose!
 * I don't know what it can be but you drive me crazy
 * All your cunning tricks make me sick, you won't have it your own way!

Trivia

 * In the E3 2009 demo of Sonic & Sega All-Stars Racing, part of the guitar solo from "Open Your Heart" was used as the theme for Sonic's All-Star move, Super Sonic. However, the song was replaced by the Invincibilty theme from Sonic Heroes in the final copy.
