I think a lot of this depends on whether or not you are a musician or interact with musicians. Every music-oriented person I know loves to explore new music.
Many people, however, use music as a means to supplement their routines. They create playlists for working out, for studying, taking road trips, etc. Usually there's a style in mind. Most people, in my experience, don't listen to music in an exclusive sense (that is, for itself, for expanding, or whatever) because they don't have a listening practice. They don't devote time to it. I'm not denigrating them, everyone has areas of focus and interest.
And the article itself is a lifestyle piece. It's intended to be consumed without a lot of thought or engagement. It's just the time and space we live in. So much competing for time and attention, and we have limited amounts of each.
I will say that This is Your Brain on Music is a brilliant book. I don't think the quote pulled from it for reference in the article does justice to it. It was written by a musicologist and is an extended investigation into why music affects us the way it does.
