Piracy: ꜱᴀɪʟ ᴛʜᴇ ʜɪɢʜ ꜱᴇᴀꜱ

recently ive started using the johnny decimal system which has helped with the chaos of my folders/files, and for me it has actually worked, everything is sorted in a very organized and meaningful way according to my own subjectivity. except for media. i tried using calibre for books, picard for music, i dont know what i could use for films/tv shows, but everything requires a lot of manual work, i have to verify the metadata is correct, or in some cases that the release is the correct one, sometimes the author isn't properly rendered, etc. is there a way to automate this? i know using something like radarr helps when you're downloading but what i am supposed to do with the files i already have?
