How loud do you play your music?

It depends on the situation. While walking on campus I tend to have my music playing full blast. And I'll glance around for curiosity to see at what distance people turn their heads.

At the apartment is a bit of a different story. My roommate this term is a bit of a stickler on noise, so I have to have the headphones on whenever he's around. If you want an idea how much of a stickler, I have to shut off my computer at night because the quiet little fan apparently keeps him awake. It's either that or I have to listen to him trying to explain in English how I don't understand his situation, or how this is not my own room but our room (or just his at this rate), etc. Because he is still learning English, this takes around 10-15 minutes as opposed to just one or two. Not that I have anything against people here in the US that don't have English as their native language, but it just doesn't help on matters like this. [/rant]

In the past, I have my speakers up a little, but not very often to the point of blasting.

Jam it back in, in the dark.
