Hard to argue against it when you get memory holed by playlist entry removals by a cloud service. Much easier living having everything at `.config/mpd/playlists` with git history.
I'm very serious. It's not a simple matter to get any sort of exportable data from these cloud services, and they won't bother to notify you that media that was on your playlist or in your library has been removed. I gave Apple Music a try for about a year. and even that relatively small migration was hellish.
I have an easy time managing a playlist through the many available audio player frontends writing to an .m3u which is itself usable as a file path list in scripts to copy the music from my library to an external device.
