Thank you @zerojay ! This is tremendous. Very easy to install, and after a minor issue with the vgm directory permissions, was able to get everything up and running....kind of.

Few issues below. Any help would be much appreciated.
*Update Recreating the autostart.sh file fixed issues 1 and 2.

Both the playmusic.sh and generatem3u.sh scripts are running without issue, but music will not start automatically after boot. I can start it by running the playmusic.sh script from the command line (or via ssh), but it only plays through HDMI port. I don't see anyplace in the vgmplay config file to point it to the Headphone output on RPI4. The playlist does not loop. Playback terminates after reaching the last item in the m3u file.
