I have a few playlists that are accompaniments to particular stories/pieces of media. Basically playlists with a narrative they follow. Those are somewhat easy to make, because then I just add any song that makes me think of the story and then I sort the songs into chronological order of which part of the narrative I feel they apply to. Then I have a playlist for political music, so I guess that’d be a playlist by topic.
Normally when I listen to music on Spotify I just shuffle my liked songs though.
