For those interested, here are the 20 songs I am working on for the jazz arrangements. For most, I am trying to stick to the melody, as I don't want to detract from Uematsu's beautiful compositions. A few will be pretty wild, though.
1) Red Wings
2) Kingdom of Baron
3) Theme of Love
4 Welcome to Our Town!
5) Main Theme of Final Fantasy IV (2-3 renditions of this)
6) Into the Darkness
7) Ring of Bomb
Rydia
9) Castle Damcyan
10) Suspicion
11) Golbez Clad in the Dark
