Smart playlist generator for Spotify

• Generate playlists based on artist, track or playlist seeds
• Generate playlists based on personal playlist as a seed
• Tune parameters like popularity, mood, energy, etc. to further customize the playlist

• Feature range calculation
  1. Get all tracks in the playlist from the Spotify API
  2. Query Spotify for different track features
  3. Calculate the 0.1 and 0.9 quantile range for each feature
  4. Use these as min and max targets for each feature
• Extract most relevant artists and tracks as seeds
  1. Find the frequency of artists and tracks in:
     • Playlist
     • User profile / listening history: short, medium, long term
  2. Select most frequently appearing artists and tracks that exist in the playlist
• Query Spotify API with the calculated seeds and parameter values
