@Mods-Free, you download and install the TRIGGERcmd agent on your computer, and create a command like this.

You get to the above screen from the GUI Command Editor, which you get to by right-clicking the TRIGGERcmd tray icon like this:

You also need to download the nircmd tool, and click that button to copy it to your Windows directory. This window will come up when you run nircmd:

BTW, I had the command wrong at first, but I corrected it in my earlier post, and in the screenshot. I also tested it with spotify and it worked.
