Wow, this truly is a nice song! I think it's so good because of how happy it is. Granted, you've done stuff like that before, but this just worked out really well. It's one of the most joyous sounding songs you've ever made! It's great to hear this tune. It doesn't seem forced or anything.
It sounds a lot like some jazz instrument. That made it pretty unique. I'm glad I was here to review it. The title does sound like something from jazz. It's nice to know you look into all styles!
