+# AppleScripts
+
+Most of these scripts usage is pretty self explanatory. For use with [GeekTool](http://projects.tynsoe.org/en/geektool/).
+
+### PlayPauseiTunesInstacastVLC
+
+I created an Automator System Service, bound to a global keyboard hotkey, which plays/pauses not only iTunes but also Instacast and VLC. Be aware that you have to create an Automator Workflow with a single "Run Shell Script" Block, which in turn opens the Script itself with osascript.
+
+It you create an AppleScript Block in Automator, the Script will not work as expected (if one of the Apps isn't running it will open).
+
+### trackchange.sh
+
+This Shell script is run by SongName.scpt whenever the current playing song changes. It will update my [Music Log](http://xythobuz.de/lastmusic).
