That's pretty easy, I made an Action Replay DS code for this just in case someone would want to rip the soundtrack :P

EDIT: By the way, some corrections:
"Rajiv's Death" is used as the theme for every Beastlord.
"Boss Battle" is really only used for Beastlords. All other bosses have different battle themes.
"Mechato" should be "Mechto".
"Mirrorshade Grotto" should be "Mirrorsand Grotto"
"Mysterious Fog Place" is used in illusion traps set up by the beastlords, the most important (and biggest) one is Depths of Memory.
Apart from the battle tunes, some other songs have their intro cut off as well.

I really appreciate what you're doing. This game has got some great music. I tried ripping it myself but my computer is too slow to run the emulator at full speed :/ Keep up the good work!
EDIT2: I found a download link for the Premium Soundtrack that came with the JP game. It contains only 5 songs, but they sound different than the in-game versions. Perhaps they could be added to the game rip as extras? :P

Thanks for the code. That should make getting the missing intros for some of the music that's only used in events easier. I'm saved in front of the Earth Tower right now, so I should be able to fix the Primal Lord battle theme intro soon, as well.
EDIT: This code causes NO$GBA to crash whenever an event voice should play. I'm using the undub patch. Does it make a difference?
