Hmm, I don't really relate to that. I actually have more music than the author, although my taste is more eclectic - I don't have anywhere near that level of OCD.
With the friends thing, it's important not to talk about the music you love to anyone who doesn't share your enthusiasm. That's a sure fire way of losing friends. Some of my friends like music, so sometimes we talk about it. Others don't, so we talk about other stuff.
I don't know anyone who's into hi-fi though.
