+¤ As per "https://newsroom.spotify.com/2021-12-01/learn-more-about-the-audio-aura-in-your-spotify-2021-wrapped-with-aura-reader-mystic-michaela/", givern person's "aura" seems to be either "orage"
+or "purple" based on above average (middle of the scale) energy and danceability together with high tempo.
+
+¤  With a list of predefined "auras" with their description and drawn graphs of parameters from songs.db one can approximate a possible "aura". But this problem is way too abstract (for me) to
+comprehend, thus I cannot propose any alorithm to calculate said "aura".
