Only massive updates with new drastic functions will have 2 levels, while other ones with minor thingies like a new mechanic will only have 1. And when it's about the music's pace, slow-paced music can have hard levels while fast-paced levels can have easy levels. Like when I used Childhood by Waterflame in my level Dark Dream. It is a slow music in a slow, though a bit hard level.

However, if with 2 is a Harder and a Demon, and with 1 it will be insane, then Fingerbang is going to be an insane.
