I use a ton but the main ones are
Airtimes (shows you when a show is airing. Useful for… Liberating…)
Lrclib lyrics. Provides LRC files for songs so you get lyrics
Opensubtitles gets you subs with options to auto download for new media
Mine is my Jellyfin.
With a good few plugins it’s gotten to the point now that my Jellyfin is my
Movie Shows And music service
Its been really fun to hunt for blurays of my favorite shows and take the time to rip them and get all the extras labeled.
Same goes for looking at bandcamp and buying CDs again.
I still have some media I liberate… I mean they won’t make blurays of everything sadly.
By hand :(
