I knew after the last JAM that you wouldn't' disappoint on volume of songs. And here we are again, 7 songs in one medley!
Your transitions between songs are totally on point. You structured it exactly how I would expect from a live band performance but in the capsule of a video game montage. It felt like an awesome credit scroll sequence. You really nailed the sound scheme too, this sounds like it totally belongs in Kirby 64, I'm surprised that I don't see soundfonts on your list of tools.
Awesome job!
