Am I the only one who goes around singing spontaneously all the time? :) - KL

You are not alone, but you just sound better when you do it than most of us.

I do find myself singing quite often. It usually happens when I'm in a really good mood or when I hear something that jogs my memory and a song lyric comes up...

I don't usually sing much, but I do hum a lot, and even whistle. I also have songs going through my head all the time.
