Or shoulder speakers? I don't like wearing headphones, I'm not a naturally fearful person, but not being able to hear things around me freaks me out. But shoulder speakers might give you your music while keeping the outside volume very low? Maybe not too late to exchange your speaker?

Becky, without knowing what you've been reading, just in my head I feel like it's the opposite, that joy is transient while happiness is more a way of existence. Joy comes reasonably easily to me, mostly from situations where I'm outdoors in flow, like motorcycling, fast descents on the bike (not that I've done that lately), distance running. But having been independently diagnosed three times with double depression, it's safe to say I'm not naturally a happy person ... if I don't deliberately put myself into joy (which usually involves NOT doing most of what needs to be done ), my natural state is pretty miserable ...
