Today's fun with arranged music goes an extra level deep. Sega's Sonic the Hedgehog CD is notorious for its pair of distinct soundtracks, as the original Japanese compositions were swapped out for the North American market with entirely new material. To fully appreciate today's arrangement, you may want to familiarize yourself with Dr. Eggman's boss themes from the Japanese and European versions of Sonic CD if you're not already familiar with them, as this track from 1994's Sonic the Hedgehog Remix, "Dr. Gigglyman", turns to them for inspiration. At least, that's what they tell me. The contrasting styles between the original music and the arranged take are so different that it's difficult to see how they can possibly overlap. Every now and then I can hear a little bit of the Sega CD soundtrack in the arrangement, but it's fleeting at best. Still, the arrangement is solid enough to stand on its own even if you can't track it to the source.
