+1 on the premise that every piece of music has an appropriate (optimum) presentation level. Many responses are in the 80-90 or 70-80 ranges, so many of us play at the level that the song demands. I wouldn't want to listen to James Taylor at 95db, but I'll blast Talking Heads Burning Down the House at 95!
Having spent some time at Masterdisk in the mastering room Scott Hull listens/mixes most music at just over 90db. Pretty loud.
Personally I'm all over the map, my dedicated listening room is double walled/green glued/rock wool insulated/Quiet rock dry walled and has a noise floor of 29db. This makes quiet listening easy.
I'd be interested to know the noise floor of your listening environments.
