Gimmick! (NES) - Sophia
Really great NES-era stuff, although I don't know anything about this game. Discovered the soundtrack while watching the documentary series Diggin' in the Carts, which had an interview with the composer Masashi Kageyama.

Also linked to the interview with the composer. (Hopefully the link worked, but interview starts around 10:20 if not. Be sure to turn on CC unless you speak Japanese!)
