After I do my Sunday Shuffle every week I keep iTunes on shuffle for the rest of the day. Sometimes I'm off and on a bunch, sometimes not.
I've also been running my iPod on shuffle over the past week or two. I use it when I go out for walks or for doing chores around the house, sometimes running it through the stereo. I was listening to it this morning as I was doing the rest of my cleaning.
Well, today both iTunes and my iPod were paused with the same song coming up next - "Impossible" by Shout Out Louds. That's never happened before. Very interesting.
