An Apple Script meant to be used with Spotify Free on Mac. If you run it while listening to Spotify, it will mute the application's volume as soon as an advertisement comes on. Once the ad is over, the volume will be set back to normal.
You can choose to run the .scpt file from the Mac's Script Editor or launch the application from the .app file. The .app file is more convenient to run than the script, and should automatically close when you quit the Spotify application. If you want to make tweaks to the script (e.g. changing the time between loop iterations, etc.), you should run the script from the .scpt file.
NOTE: In certain circumstances, running this application may lead to heavy CPU usage by the runningboardd process. Please be aware of this if you choose to use it.
