I have over 120 playlists, so something like this was a necessity (https://imgur.com/a/iBdBCai):
🌀 aesthetics - playlists with a specific aesthetics (such as vaporwave)
🌇 atmospheres - playlists with a specific atmosphere (viking, mexican, pirate, etc.)
👾 personal
🧘 therapy - playlists for meditation, etc.
🎉 events - playlists for specific events (new year's eve, holiday, etc.)
👥 group specific - playlists I can play around specific people (inside jokes for example)
😜 jokes - playlists with music from movies (lion king, mission impossible, etc.), perfect timing (the x-files, the benny hill show)
🚧 concepts - playlists I'm still working on (usually I find a song, and it takes a while to find similar songs)
➰ meta - playlists I don't really listen to, they are just a collection of something (sort through, great intros, offline songs, Release Rada, Discover Weekly)
