It was this guy.
I was looking at his laptop and there were shortcuts that I didn't know. Asked him about one program and it was a mania like rhythm game which auto generate the "beatmap" (I don't know what to call it, but I'm pretty sure you'll understand). But he says, "this one is not so good, there's another one that fits the music more." Then he closed the program and moved his cursor to this pink circle shortcut with three letters and an exclamation mark and open it. I was enlightened.
