Have you ever been in a mood for a certain genre of songs but didn't want a generic playlist or to sort through your whole library to find them? This might be the solution for you!
Check out this website (which is free to use): organizeyourmusic.playlistmachinery.com/
It will organize your music with several different factors: like genres, decades, popularity, styles and let you see those lists, and instantly transform those lists into spotify playlists for you to jam along to
This is also super cool if you are just curious as to what genres you listen to the most (it lists all the genres you have saved in your library, and the most popular ones are at the top of the list), or what genres exist in your library that you didn't even know about
It even lets you graph your library if you really want to compare and examine your music
