Alright. Im with you, ive been dealing w this too for a while and i get stressed about it. First off i use spotify (i use youtube to organize instrumentals and deep tracks and souncloud for underground rap & mixtapes bc they dont have those on Spotify).
So i also listen to vast amount of genres, not a hundred different genres though lol i didnt even know a hundred existed tbh
But i used to group it by genres and this didnt work. For example, i have alot more hiphop songs and classic rock songs then i do jazz songs for example. So I'll end up with a playlist w significant amount of songs (hundreds) and then a jazz playlist with only a hundred or so.
Well i would play the hell outta those songs and it wpuld get old. It was disorganzied and stuff. I deleted my playlists and now am in the process of categorizing.
Right now, i have 73 playlists on Spotify with 100+ songs at least in all of them except a few. And im categorizing by genre and certain styles or sub genres within that genre.
Rap is my favorite, so i have 20 or so playlists of jyst different types of rap (old school rough, old school chill, 80s rap, trap lit, trap wavy, wavy rap [not trap], happy/bubbly rap, rap love, trap love, party mix [for the ladies], rap mixed w soul (lovveee), etc i dont feel like naming them all but there's alot more). Those arent final drafts, im just caregorizing and not really relistening to much and then im gonna go through and put them into real playlists.
I think I'm gonna base these playlists on moods/vibes but alot of playlists are going to have the same genre in it. For example i have 2 playlists (out of 73) that are pretty much finalized. A wake n bake playlist (my most popular, its a mix of different genres, im really proud of it) and an inner demon playlist (rap songs that represent how i be feeling on the low sometimes, dark lyrics and stuff).
And I'm also splitting up for other genres obvipusly lile general/chill classic rock, rough classic rock, alternative rock, indie rock, old school regaee, new school regaee, blues, jazz, classical music (beetoven & mozart type stuff), new aged soul, old aged soul, funk, old school country, new aged coumtry lit, new aged country slow, even a standup comedy mix which im not changing its balling. Theres alot more but you get the point.
It depends on how much music youre sorting and what platform. Spotify is dope if you use your phone bc you can download songs in your playlist (so you dont need internet to play). But a hidden perk is if you come across a song that you think might be in one of your other many playlists, if it is and the playlist is downloaded, there will be a green circle w an arrow so you know its on another playlist. This is helpful to me to help w no overlap so i dont have repeat songs in various playlists.
Last thing, i created a temporary playlist where i store excess songs from older albums and can go through and listen and add and it helps alot. Just dont download that paylist bc you cant see if its added elsewhere when going through it. And i try not to listen to much to the songs already in the playlists rough drafts i made so they don't get old. So i have 3 playlists finished and 70 that are rough drafts and used as sorting so i can categorize them into finalized playlists later
