The whole “what is art” question has different answers for different people. Yes, for some, music is communication, but when I listen to metal in the gym it’s an adrenaline boost. When I listen to brain.fm, it’s for focus. When I listen to a rap song with an MC that’s great at storytelling, then it’s communication. Sometimes it’s just a utility though. I’ve played music for about 30 years - live, in bands, in my bedroom - played many instruments, written electronic music, made lots of noises. But I’m not always trying to communicate something. In fact I’m sometimes scared I don’t have anything good to say with my music. So I just play it.
