Spacey

Spacey gives you keyboard commands to move app windows between Spaces.
Spacey is that utility that will allow you to show the world what your top 5, 10 or 25 list is at any point.

Upon publishing your playlist(s) to the internet, anyone clicking on any song in your list will be brought to the Gracenote CDDB to learn more about the song and even what CD it is on!
