Sorry if this has been mentioned before, but I was stuck on a long drive recently and played the following game - helped pass the time.

I have every Prince CD (and many boots) on my iPhone - I selected all songs by Prince in alphabetical order (you can start anywhere). When listening to a song, try to figure out what the next song will be. You'll be amazed at how many you miss.

I thought I would be good at this game - but I sucked.
