I definitely just wear one of my headphones to the zune and leave the other one out. although, if someone looks as if they're going to approach and want to have some meaningless conversation, I put the other in and pretend that I am unbelievably into whatever it is.

Headphones are great for music when buzzed. I like the surround sound/whatever feeling. It seems to compliment the smoke

I also really love listening to LPs...digital music is a curse on the world.
