As far back as I can remember, I've "played" music that I remember in my head when I didn't have real music to listen to. I have songs stuck in my head 24/7, I don't even know what it's like to not have music playing in your head. What goes on in the brains of people who don't know this feel?
iktf, I've had Daddy Don't Live In That New York City No More stuck in my head for the entire evening and I'm doing my best to watch movies.
