[Yesssss]

typically I'll only stop stepping a song simply because I don't feel like continuing with it. Sometimes I will randomly continue it later and finish it (both of my '11 Fall files have portions that are about 3-4 years old)
It's pretty rare for me to stop stepping something because I don't know what to do with it. It's mostly because I don't care enough to put the effort into making it good.
