This song in particular is not by Jun Senoue, it was composed by Tatsuyuki Maeda.Jun Senoue made banger Genesis songs before Sonic 4. Wish he stopped using those God awful VSTs and use something like Furnace for the Genesis-style tracks.
The whole Phantasy Star The End of the Millennium is a MASSIVE BANGER, my favorites being
The End of the Millennium (Main Theme)
Meet them head on! (Normal Battle)
Thray (Thray/Rune's Theme)
Defeat in a blow! (Boss Battle)
Behind the Circuit (some hi-tech dungeons)

*Dark Falz is the correct romanization. Dark Force is wrong.

(fun fact: it is speculated that both acts are composed by Jun Senoue. DANG, I didn't know it, learned it right now. If it is in fact his... no wonder it is my favorite Sonic 3 song.)
Magnetic spheres is so fun, too bad at suck at this bonus stage so much and can't listen to the song in-game lol
