MAIN TOURNAMENT
Main Title (Orchestral) (Panzer Dragoon) vs. Pokefloats (Super Smash Brothers Melee) - Not particularly close. Oh, wait, that's not the Parasite Eve Main Theme (Orchestral)? Silly two-word games that start with P... Eh, main themes still win the day, though not by as much.
A World in Crisis (Final Fantasy VII) vs. Terrible-Monster Attacking Crew! (Wild ARMs 5) - Huh. World Crisis is kinda a weird nom.... works fine in game, but bounces back and forth a lot out of game. The WA5 track is consistent and fun. I feel guilty about this vote, but so it goes.
A Despair-Filled Farewell ~ Battle with the Colossus~ (Shadow of the Colossus) vs. The War Song (Sam & Max Season 1) - War Song is cute but not quite Tom Lehrer level, which it clearly wants to be.
Sonic Boom (Super Smash Brothers Brawl) vs. Thema der Irismaschinen (RozenKreuzStillette) - Eh. Irismaschinen has some nice parts, but I really don't like the electric guitar. Voting the cheese.
Main Theme (Orchestral) (Parasite Eve) vs. Musicbox (Silent Hill 2) - Ah, here's the PE track.
Karma (Tales of the Abyss) vs. The Oath (Final Fantasy VIII) - Tentative vote since the linked version of Karma is currently the one with the breathy bad singer. Vote will change if it's vs. American Karma with the sweet guitar riffs.
Bonds of Sea and Fire (Xenogears) vs. Murdering Princess (Wild ARMs ACF) - Murdering Princess is okay and all, but it takes a bit more than that to beat a good piece of the XG soundtrack.
EXEC_LINCA/. (Ar Tonelico) vs. The Mountain of No Return (Wild ARMs 5) - Mountain is nothing special, LINCA is at least interesting.
FAILURE BRACKET
Eternity (Blue Dragon) vs. Finale Toccata (Castlevania: Symphony of the Night) - Eternity wins even when winning means losing~ (More seriously... Finale Toccata is good! It gets overplayed in the upside down castle, sure, but it's a dramatic piece with a nice long loop. Eternity, meanwhile, is AWESOME IN BOTH DIRECTIONS.)
ANIME
XTC (Witchblade) vs. Zero (World Destruction) - Random comment: The World Destruction OP from the DS game is actually pretty awesome, and better than Zero. But Zero's good, certainly better than XTC.
Read or Die Theme (Read or Die OVA) vs. Rolling Star (Bleach) - ROD theme is only okay, but I actively dislike Rolling Star.
