If you don't like or don't want to explore music, that's your prerogative. It's a hobby and a skill you can build like anything else. You could have the one pop, country, or metal song/artist you enjoy and not branch out, it's perfectly valid, but if you like the sound of a particular song or genre there are many songs in other genres that will have the same vibe. It's just up to you to explore. I think part of the problem here is that a "genre" is a vague, idiosyncratic definition that overlaps with every other so-called genre.
