Great Song, but...
I played Castle Crashers from beginning to end with myself, 1, 2, and 3 friends (separately), and I never heard this song. Its an amazing song that sent chills up and down my spine when I first listened, but the title says its from Castle Crashers, and is used in the Arena battles, but still, I never heard it. Oh well, doesn't make it any less of a badass song. If I am wrong though, feel free to correct me, and let me know when this song is played in the game.
