Tired of Crush 40 yet? I hope not, this is a Sonic vocal track list and enjoying them is mandatory.
Sonic Adventure was absolutely mind-blowing at the time it came out, and this song played in part during the menu idle cutscene and during the Perfect Chaos fight. Put two and two together, and you have Open Your Heart as one of the best-remembered songs in the entire series.
I could go on and on about how awesome this song is and the memories it evokes in Sonic fans, but there's no need. Open Your Heart is great for what it is. It's got that perfect mix of edgy, uplifting, and hype-inducing that makes it one of the best vocal tracks in the entire series.
