After seeing the epicness choices Locke made over on his blog i decided to do my listing.
Organization XIII Theme: Kingdom Hearts II. Trying to learn this song on keyboard, it's not too hard but i just dont have the time to practice on it haha.
Hollow Bastion Theme: Kingdom Hearts. Notable mention goes to the combat theme from that game for that stage as well.
Street: Mortal Kombat 3/UMK3. It's actually a remix of the Courtyard theme from MK1.
Mini Boss Theme: Majora's Mask. Most memorable thing about this theme is when Skull Kid starts fasting the moon's descent and you have to quickly play the Oath to Order
Song of Healing: Majora's Mask. It's so dark and depressing but it was written to heal the troubled souls of people, when you listen carefully to it you can feel their pain, all their suffering, then you begin to feel it all melt away.
Theme of Ghosh Rode: Azure Dreams. The biggest douche bag i have ever laid eyes on when i was a kid, to sum him up, in terms of appearances he looks like James from Pokemon, this guy and Maximillion Pegasus but with a way more douche bag personality.
I'll add more later on, also im leaving out Final Fantasy tracks, i'll save that blog for another day
