mine doesn't bitch ... i jusr listen on headphones out of respect as I know she does not care for it. never once she told me to turn it off if it was on the loudspeakers.
I don't mean that you should do it to annoy her, but I mean, the way I do it is if I play what I like, they can play theirs for an equal amount of time. It seems to please all involved.
I prefer a good stereo with good stereo speakers for a good stereo sound! I will utilize earplugs erk at work, though, as people shouldn't see me listening to music most the time I'm there.
