Jun Senoue on Twitter:
Fan A: Hello Jun, I have a question. Sonic Adventure’s soundtrack have very unique and cool track names. Who decided on the names?
Jun Senoue: I named the ones I composed or arranged. Kenichi Tokoi and Fumie Kumatani named their compositions as well.
Fan B: I love when tracks have a unique OST name rather than just the stage name, makes them more interesting somehow.
Jun Senoue: I know what you mean but I gave up to do that when I worked on Sonic Heroes.
Fan B: I understand, I imagine it’s hard to come up with names sometimes or you are just composing with the level environment in mind.
Jun Senoue: Actually I was too busy when I worked on Sonic Heroes. Had to work on SFX and voice files for all consoles and such.
