How do yall organize ur music/ spotify

I used to organize all my music by genre, and i had a million playlists but only listened to like 2. For some reason i felt the need to save every song i knew, as if i didnt save it that meant i didnt actually know it. I recently realized that js bc it isnt saved doesnt mean i dont know it, and that i was wasting a lot of space by saving all that shit i didnt listen to but used to. So i made like 4 playlists of music i actually listen to, and organized them by what general sound im looking for. Heavy? Rythmic Rnb? Classic rock? its still genres, but more like 4 genres that are similar put together. Ill update in like 2 weeks as to how its going

but how do you organize yours? are you a 1 playlist person like my bf, or a 1000 playlists person?
