No, 357Magnum, this is not about +P!
I have a relatively robust music collection... mostly of filetypes .m4a and .mp3. There is one indispensable tool that I recommend to tag and rename a music collection and it does not run on Linux. The name of that tool is, strangely enough, mp3tag and you can give it a whirl here: https://www.mp3tag.de/en/ .
This tool makes it a delight to properly tag your files, and I also use it to delete any files with bit rates < 320 Kbps. When I purge these 'inferior' files, I am often left with empty directories. These empty directories can be somewhat difficult to remove manually, and I sure don't want them to continue being backed up by my nightly backup processes... and I really don't want these empty directories to be indexed by my streaming music server software.
So, as an exercise in futility I present 'try 0.1' at a PowerShell script to delete any directories in your production music collection containing no music files:
Change the file extensions to suit your liking.
There will be 'warnings' the first time you run it because certain files do not exist yet.
Log files, etc. are created @ C:\TEMP

# This creates some test data under C:\a (make sure this is not
# a directory you care about, because this will remove it if it
# exists). This test data contains a directory that is hidden
# that should be removed as well as a file that is hidden in a
# directory that should not be removed.
