Do One Thing Well: Each program should focus on a single task and perform it effectively.

At the moment im not hosting a music server, but used to use Navidrome, it worked fine and used a small footprint.

Having all in one it’s more issues to solve, if something breaks, everything breaks.
Having all on Jellyfin is more convenient.

But adding hundreds or thousands of songs along with movies and episodes will create a huge database, more resources used, slower searches

Adding to this DDL store the content for a limited time. Some of the content after one week is almost impossible to find

For me there’s no “get caught”, and many stuff are only available trough torrent, like some old/obscure movies (some could take a week to download), other only trough DDL like some UK TV shows.

Also for automate software like Radarr/Sonarr you only have torrents or nbz
