When I first heard Ultimate Sweetie Belle I was in my silly phase where I had trouble admitting to myself I liked something if it was "dubstep". I got better. Still, I always thought "You know what'll make this better? MORE ORCHESTRATION."
So there you go. Is it as hardcore as original? No. Is the brass even close to the wubs? Hell no. But it was really fun to make.

Big thank you to My Little Rock Band. From a certain point I just started using their video for the notes and beat.
