Final Fantasy IV
And so we enter the very best of the very best, the Top 10. And it leads off with the holder of the coveted award for "best video game track that shares its name with a major sports team".
Put it this way: This is the first track in Final Fantasy IV after the iconic Final Fantasy title screen music--and that means that as soon as you start up your first game, within 5 seconds you know beyond any doubt: this game is going to be awesome. And lo, it comes to pass.
There is an unstoppability to this song that I love. Even if you've never played the game before, as soon as you hear it you cannot help but vizualize the boots of an army beyond number, marching in unison toward irresistible victory. That's what makes this one of the heavyweight contenders for the "best music for a football team to run onto the field for a championship game to". We will not be stopped, this music says, emphatically.
It's also Cecil's theme music, of course, and that's appropriate, as the things I said above fit his character. He's a determinator; he marches forward no matter what stands against him or what people tell him he can or can't do. His king, who raised him from childhood, turns into a despicable bastard? Fine. I'm outta here, and I don't give a damn what you think, Kain. Only way to do anything about that asshole Golbez is to haul my Dark Knight ass up Mt. Ordeals and become a Paladin? Fine. Let's do it. Suicide mission to the moon is humanity's last hope? I'm all over it. That's Cecil, and this is his music.
And so really, and this is very impressive, this music reasonably can fall into three categories: atmosphere music, character theme, and Very Definitely Final Dungeon (yes, it is the music the first half of the Very Definitely Final Dungeon is set to).
