I don't tend to listen at any particular genre at a set level but adjust the dial accordingly if the playback gain is low, mind you I'll give it some beans if on my own.
If my lovely lady has been out she enters the lounge scouting the room for the cats before anything else, then she speaks to the dogs (unless they're with her), says a dramatically "HELLOOOO!" And creates chaos!
If the music is at 'realistic' volume she'll give me a withing look so I drop it by a few db then she tells me everything about horses, who owns her money, how misbehaved some of her riders have been then the TV goes on.
Most often when she comes in I'll drop the volume and pretend to take interst in the banal regurgitation of the days events whilst listening to tunes until her mother calls, I can hear the MoL through the earpiece ten feet away and even with a decent level on the stereo because she sounds like an an inebriated raven that's bellowing out opera after huffing helium..
