The only problem with what you said is that Drossin includes Invincibility as one of "his" tracks. According to the 2009 interview
he said he just composed the "Knuckles theme" (S&K Knuckles) and the "Sonic theme" (S&K Title) (as proven by Sega Tunes - Virtual Sonic and ICEKnight's hack of MD Sonic 3D) and, in the 2008 interview
, says that Setsumaru handled the arrangements of the latter theme, including 1-Up (as proven by ICEKnight's hack). So wouldn't Invincibility also be Setsumaru's arrangement?
"I only composed single versions." - Drossin
"The music was composed separately and input for the genesis by someone named Setsu (I think). didn't do any sound efx for Sonic 3." - Drossin
Looking closer, there's one thing that I admit I completely overlooked: Virtual Sonic was recorded in 1993
; it was just released three years later. So all the arrangements (not just Invincibility, 1-Up and All Clear, but also S&K Knuckles and S&K Title) could be Setsumaru's period. At the very least, the fact that those compositions existed before S3's release with the intent to be used in-game (be it S3, S&K, or S3 in the whole sense) should be the reason for Drossin's "Sound Special Thanks" credit in S3. Drossin being a "Music Composer" in S&K and S3&K then should be because those compositions were then implemented/put into place in the game. In actuality, everything he did was originally composed outside the context of the game the music wound up on. No wonder he's so bewildered about this game.
If I ever spoke with Drossin I'd like to know just how much of MD Spinball's music is his. Drossin was the only one from the Institute; Blum and Coburn were from the Multi-Media Studio (different from OUI Multimedia) (credits taken from manual).
Agreed. We've pretty much got all we need/can get from Drossin that made it into the final version, and that's all we should ever really ask of him as Sonic fans. If anything we should continue the chain to Setsumaru. The beta credits from S3&K are an excellent place to start, as the final part (S3 All Clear) was replaced by S&K All Clear (a Setsumaru arrangement), making the former two potentially Setsumaru's as well. Given that, the tracks chosen for the medley could be the versions Setsumaru arranged. Drossin said he did "remixes;" he didn't say they were the "Act 2" versions.
"That would be Setsu doing the remix." - Drossin
Mario Kart 64's voice sample credits are another good example of crediting only what is new. In the Japanese version, Charles Martinet (NoA) (Mario), Tomoko Maruno (NoJ) (Kinopio/Toad), Asako Kozuki (NoJ) (Peach), Julien Bardakoff (NoE) (Luigi), Thomas Spindler (NoE) (Wario), and John Huraton (NoA?) (Menu Voice) are credited, but the voices of Yoshi, DK and Koopa/Bowser are not because they are based/created from pre-existing sound effects (Yoshi - SMW - Koji Kondo) and voice samples (Koopa/Bowser - SM64 - Isaac Marshall). When Mario Party 1 and 2 were released, not additional voices for Toad, Luigi or Wario were necessary, so Maruno, Bardakoff and Splinder were uncredited (Eriko Ibe did Baby Bowser, not Toad). As for the US version of Mario Kart 64, Martinet replaced Huraton (as well as Bardakoff and Splindler), Leslie Swan replaced Kozuki and Isaac Marshall, despite having done the voice of Bowser (and most likely DK since both were replaced/overwritten around the same time) is only credited because he replaced Maruno as Toad.
In keeping with the forum topic, Buxer is confirmed to have worked with MJ in creating S3's Staff Roll (the basis of Stranger in Moscow) and worked with C. Cirocco Jones
(Scirocco) on the composition and arrangement of a "Level 2" and "Level 3." Combine this with the fact that Buxer's usual role when involved with MJ was arrangement (ex. HIStory album) and it can be assumed that Buxer was the one who did the majority of the production work (MJ was more-or-less a coordinator). He is listed first on the list after all.
