Streamed music is kind of tricky, but I was able to get some music files out of the GC version of the game.
Each DSP file had like 16+ tracks in it. Most of them are just individual sound effects, with two music tracks each. I'm not sure if the tracks were meant to be combined or not, but most of them sounded better with the two mixed together. The DSP software really knows when to play what. Regardless, I left the two individual tracks and included the combined track.
There are a few songs where there are two versions of it. (ex: japan, japann) As I haven't played the game, I don't know if one was meant to be a night time track or what, but looking at the waveforms the japan and japann pairs seemed identical so I couldn't tell a difference in the songs.
