Spacey is a software utility that will work with iTunes and your smart playlists to not only compile a top 5, 10 or 25 list, but eMail them, add them to iCal or send them to your iDisk. The software works closely with your smart playlists to build a "hit list," which can be shared with the world. If you don't have a .mac account, Spacey will send your compiled playlist(s) to an FTP site of your choice.
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!
