How about I listen to 50 year-old rock music at work?
It's sounds like interesting music but why listen to it at work?
I'm used to banging my head to the music when I work. I love it.
You shouldn't disturb others at work with your music unless you know everyone is OK listening to old rock music.
I'm only listening to this with my earphones and I don't bother anyone. Why should I stop?
Oh, if that's the case, then knock yourself out. Don't take that literally, I think you should refrain from "banging your head" to the music at work. By the way, I have always liked your taste in music.
