The title's worth a thought or two. When you're alone or not involved in activites meaningful to others, basically the whole world is running without you. This is pretty fascinating, overwhelming, and a bit sad at the same time.
Okay, that solves that mystery! I don't know if there are any samples on here anyways, and I'll assume the "everyone within this world is doing something without me" part is either Gaz or Brian with a vocoder.
