Probably my favorite of them all if I were forced to choose, a remix of this song was what got me interested in Zun's music/games in the first place. Yukari also ended up being my favorite character.

A couple more favorites. These are from the 6th game, the first one for the Windows platform.

This one is from the secret stage of the 5th game, you need an emulator to play the first 5 games.

i always liked the FF7 boss battle theme.

but I think my favorite, most memorable, would be zelda a link to the past.
