Implements a Widget for Spotify in the Notification Center of OS X 10.10 Yosemite
It uses the AppleScript API for Spotify to get the necesseray information and control it.
Watch Screenshot.tiff for preview.
Download the project, copy the "SpotifyMain.app" to your Applications folder and start it. Maybe in "Today View" settings the widget still needs to manually added.
If you have already installed one version restart the Mac, replace the old SpofityMain.app with the new one and start it.
