Sifts through the nauseating pile of tracks I attach my characters to

For an insert/encounter theme (like those little tracks you here when you talk with a certain character in the overworked) tied to Odd, I have two very different tracks in mind, but feel they both fit him equally: Sax Quartet, a track from Cowboy Bebop (https://youtu.be/x5gzIzJe0Xg) and this overworld theme from Kirby (https://youtu.be/MazQsrgp0rs)

For battle music, I tend to gravitate towards something by Tool, particularly Schism and Lateralus

As just a general, all around character theme for him, though, No Surprises by Radiohead almost always springs to mind
