How do you organise your music playlists?

Mainly aimed at those who use Spotify, Tidal, or any other streaming service like myself, but those who pirate music should still feel free to answer!

How do you organise your music library? Creating playlists is pure torture, in my opinion, because there are so many songs that overlap in genres. I've tried creating lists based on genres, but I'm the type of person to listen to multiple genres in one session so the switching between playlists kinda becomes inconvenient. Same with based on mood, I can still listen to discoesque or fast-paced songs when I'm feeling sad.

Genuinely considered hiring somebody to create the playlists for me, lol. I know having 800 songs in one list is clunky, but having everything in the same spot is a source of relief. Ugh.
