This is really great! So sunny and catchy and fun, I loved this one. I would never have noticed the 2-instrument limit; you made it sound really full with the different layers of jangling guitar. I really like that main riff. As you know, I recorded some of the “CHU-PA-CA-BRA” backing vocals for this song without any other context, and I was really curious about how they would be incorporated. Glad to see you’ve put all the guest vocals to good use. I probably would have given this the side-eye as far as the challenge goes if you were a contestant... well, then again, maybe not, since clearly you did put a lot of effort into writing it to fit the concept. But fortunately you sit on the throne of judgment this year and can do whatever you like.
