I think you mean this one:

http://www.youtube.com/watch?v=zUQlbwRIf8Q (Moon & Mars ~Sukarabe Fight BGM 2~)

But yeah, this game is good Game Gear comparison material, especially this set of 3

Moon & Mars ~Sukarabe Fight BGM 2~ is similar to:
-Opening/Scrambled Egg Zone [Sonic 2 (8-bit)] --> Therefore it's Hataya's
-Title Screen [Sonic 2 (8-bit) and Sonic & Tails/Sonic Chaos] --> Therefore it's Hataya's
-Electric Egg Zone Act 3 [Sonic & Tails/Sonic Chaos]
-Underground Zone [Sonic 2 (8-bit)] --> Therefore it's Hataya's
-Sky High Zone [Sonic 2 (8-bit)]
-Crystal Egg Zone [Sonic 2 (8-bit)]
-Invincibility [Sonic 2 (8-bit)]
-Bad Ending [Sonic 2 (8-bit)]
-Mecha Green Hill Zone [Sonic & Tails/Sonic Chaos]
-Staff Roll [Sonic Drift]

Moon & Mars ~Sukarabe Fight BGM 1~ (http://www.youtube.com/watch?v=zhyNeT38A_U) is similar to:
-A fair amount of Sonic 3 [from beginning drumbeat]
-Act Introduction (Sonic 2 [8-bit])
-Aqua Lake Zone (Sonic 2 [8-bit])
-Gimmick Mountain Zone [Sonic 2 (8-bit)]
-Boss [Sonic 2 (8-bit)] [BOTH SMS and GG]
-Good Ending [Sonic 2 (8-bit)]
-Final Boss [Sonic & Tails/Sonic Chaos]
-Scrap Brain [Sonic Drift]

Moon & Mars ~Sukarabe Fight BGM 3~ (http://www.youtube.com/watch?v=_wPSKHMUj-M) is similar to:
-Death Egg [Sonic Drift 2]


Another good comparison is Earth ~PETO Fight BGM 1~ (http://www.youtube.com/watch?v=Bcuv3M5L8kk)
-A fair amount of Dr. Robotnik's Mean Bean Machine

Also,
Gigapolis Zone [Sonic & Tails/Sonic Chaos] is similar to Spring Yard [Sonic Drift] & Course Select [Sonic Drift]
Aqua Planet Zone [Sonic & Tails/Sonic Chaos] is similar to Green Hill [Sonic Drift]
