random, yea. if nobody else is around then i usually turn it to full and turn my whole bloody life into a music video, but otherwise, if somebody else is around, i keep it 'pretty low'. your choice?? oh, and what do you think about when listening to music, too?
I tend to turn it up where I can hear it but it doesn't blow out my ear drums or cause me to lose my hearing long term into the future. I tend to listen to most things very low, where I can barely hear it but not drown out the world around me.
If I'm in public probably low but in my room I would probably have it at 80% because listening to rock music at full volume hurts your ears. Overall depends what song it is and where I am.
