I have the bad habit of overplaying songs I enjoy, forcing me to take a break after I've relooped them to the point where they've crumbled into plain noise. When that happens I cycle into a new set of songs, and as a result, my playlists tend to be titled not by genre or artist, but rather by date. In that way, a Spotify account is similar to an accumulation of geological layers, with music in place of sediment.
