My use case is maintaining playlists playable in a car audio, where paths must be relative to the playlist file. On playlist export, MEU remaps the paths relative to the playlist file. And spot missing, invalid entries so to fix them, invalid entries are marked red on playlist import.
For Fedora/SUSE or other RPM based distros, I have a copr named "teknoraver/meu" with the packages.
Feedback is welcome.
