All I can tell you is that if my program includes a function like fnAdd(x,y) the fn prefix doesn't necessarily stand for function, more likely f---ing where it's like in my mind I'm thinking "just fn add the damn numbers, and don't give me no grief about it".

It has to be your idea, though. I just suggest music because it's a vague thing. If "music player" is what you come up with, you see? If it's me, my issue is that to start a project I tend to make a blank screen and stare at it with the comfort that it's blank and therefore no bugs in it, otherwise I'll cry because I kinda suck at making programs.

Music.
