I completely agree with your evaluation of the music. Konami consistently put together outstanding music in the video games of the 16-bit and PS1 eras, and the remixes that the Kukeiha Club (the band, not to be confused with the "Konami Kukeiha Club" sound team) did were sometimes just as epic as the original songs. Most of the "best of the best" songs came out of that Twinbee franchise.

Twinbee really brings back some twin good memories, as I spent many hours in college either playing those games (including Detana Twinbee) or just listening to the music.
