Great question. (Al)most all of my in-person social interactions involve music; there is some chatter and on occasion a serious discussion but it tends to be secondary to the music itself.

I'm not particularly fond of or good at small talk. I'd far rather delve into beliefs, politics, anecdotal anomalies, and so on, but I think most people would rather save those discussions for their really close intimates. Assuming they do have those discussions. :)

Frankly, I suspect that the main reason that there are not more discussions of the kind of thing I like is that there an element of discomfort, if not actual fear, in it. For me, the frisson of fear adds spice.
