I happen to be extra expressive when I play - wide range, of course, not just loud - but when there is a part of a song that is meant to be loud (like, say, the very end of Philosophy) I tend to play it extremely loud because, I don't know, it feels wonderful.
Of course, I think my rugged manliness loud playing was just a bit too much for the piano, and one of the hammers broke. Should I tone it down, or is this more common than I'd expect? :c
