Steps to Build the Recommendation System

1. Data Extraction:

   • Fetch detailed song information using Spotify's Web API. This involves accessing attributes such as track name, artist, duration, and audio features.
   • Example:

     sp = spotipy.Spotify(auth_manager=SpotifyClientCredentials(client_id=os.environ["SPOTIFY_CLIENT_ID"],
                                                                client_secret=os.environ["SPOTIFY_CLIENT_SECRET"]))

2. Feature Engineering:

   • Select essential features for recommendation, including danceability, energy, key, loudness, mode, speechiness, acousticness, instrumentalness, liveness, valence, tempo, duration, and popularity.
   • These features are crucial for understanding the musical characteristics that drive user preferences and recommendations.

3. Model Training and Recommendation:

   • Utilize machine learning techniques, such as cosine similarity, to compare user-selected songs with the dataset and recommend similar tracks.
   • Example:

     user_selected_songs = [
         {'name': 'Come As You Are', 'year': 1991},
         {'name': 'Smells Like Teen Spirit', 'year': 1991},
         {'name': 'Lithium', 'year': 1992}
     ]
     
     recommended_songs = recommend_songs(user_selected_songs, all_songs_df)
     print("Recommended Songs:")
     for song in recommended_songs:
         print(f"- {song[0]} ({song[1]})")

4. Model Evaluation:

   • Assess the recommendation system's performance using metrics such as precision, recall, and F1-score.
   • These metrics gauge how accurately the system predicts user preferences and similarity between songs.

5. Deployment:

   • Deploy the recommendation system as a web application using frameworks like Flask or Django.
   • This step involves integrating the recommendation model into a user-friendly interface accessible via web browsers or mobile apps.
   • Example:

     @app.route('/recommend', methods=['POST'])
     def recommend():
         # Recommendation logic here
         return jsonify(recommended_songs)
