I think you do have a point about the replayability of music versus movies but at the same time I share my server with about two dozen friends and family so its good to have some variety in there along with having a good selection for when you get that random thought about a movie and want to watch it rather than spending 20 minutes finding and adding it to your server

Radarr and sonarr also handle the naming and organization but this all relies upon the files being properly named which can be a chore with music as you regularly see remixes, sample albums, compilation albums, singles, covers, extended play, radio play, censored, uncensored, etc not to mention the quantities of songs out there by artists of varying popularity, which is the root problem with music databases not always finding a match, matching incorrectly, or your downloaded album having songs from multiple different sources that the uploader lumped together. You very occasionally run into this with movies too but its typically because TMDB or whatever source not matching the studio on the release year when a release is delayed.

This probably isn’t much of an issue for you if you’re ripping your own music but that’s becoming more and more rare these days with the transisition away from physical media. I actually bought a blu-ray RW drive for my PC with the intention of ripping DVDs and Blu-rays but gave up because of the work involved (encoding in HandBrake) if you wanted anything but Remux quality.

I honestly wish the days of Napster came back, but I have had good luck with SoulSeek and have read that its possible to integrate with Lidarr but haven’t tried yet. Im sure things will get better in time as these streaming services try to squeeze their customers more and more.
