I don't mean to offend your interests or activities - I'm trying to make sense of the world we express through words. So far, I'm having difficulty justifying the status of a hobby of listening to music. It may be pleasant and even euphoric, but it seems too passive for such a definition. It's an activity and a way to gain pleasure and spend time, no doubt. I have no difficulty calling reading books a hobby because it requires active participation - otherwise, no reading occurs, or, perhaps, no understanding of what you've read, which is the point. But listening to music - at least, if you aren't engaging to it actively, with all of your mind's attention - is hardly an exercise in activity, especially when you do something while listening to music. I've never heard people calling taking hot showers a hobby, and most people won't call eating their hobby either. So, why is music-listening on the list?
