Everyone has a worldview. It’s just the way we understand the world. The way we see things. You know how people talk about looking through “rose colored glasses?” Those glasses are the worldview.
One of the things I like to do is collect sections of lyrics that, in and of themselves, are nice sections, but, when there are enough of them, can be pieced together to form a worldview. Ups, downs, and everything in between. It can all be found in songs because it can all be found in life.
