Spacey for Mac

From If Then Software:

Spacey is a utility that will allow you to quickly compile any of your iTunes smart playlists into an eMail or iCal event. It also allows basic control of iTunes, allowing you to double-click a song in the Spacey window to start play. Spacey will report the title, artist, last played count and rating in the Spacey window. As far as eMail and iCal, it will post the rank of the song, title and artist. Spacey can rate & eMail your hits from coast to coast! If that's not enough, Spacey can also publish your playlist to your iDisk!
