Latest version does support these generic keys:

APPCOMMAND_BROWSER_HOME
APPCOMMAND_BROWSER_REFRESH
APPCOMMAND_HELP
APPCOMMAND_MEDIA_REWIND
APPCOMMAND_MEDIA_FAST_FORWARD
APPCOMMAND_VOLUME_DOWN
APPCOMMAND_VOLUME_UP

Windows still doesn't forward such commands to Muso when minimised, and I cannot find a workaround to that.

Great work.
Take a look at the free available open source code for this tiny utility: GitHub (https://github.com/reeve/WinSlim & https://github.com/reeve/SlimCliLib).
It's a bit outdated, but still works (I'm using it right now). Remarkably, it not only manages to completely overtake and intercept the keyboard stream, but works - not only while minimized, but also from any desktop. In fact, changing the local volume doesn't work anymore while this little sucker is in place. Even turning the volume knob on my Dell monitor now changes the volume on my LMS docker installation

I have no Idea how he managed to achieve this, but somehow he did, and I'm sure you as a programmer can read the code and figure it out.
