Function for finding Spotify songs. Sample code for my Medium article: "How to build an amazing music recommendation algorithm."

find_song.py

from spotipy.oauth2 import SpotifyClientCredentials
from collections import defaultdict

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


def find_song(name, year):
  
    """
    This function returns a dataframe with data for a song given the name and release year.
    The function uses Spotipy to fetch audio features and metadata for the specified song.
    
    """
    
    song_data = defaultdict()
    results = sp.search(q= 'track: {} year: {}'.format(name,
                                                       year), limit=1)
    if results['tracks']['items'] == []:
        return None
    
    results = results['tracks']['items'][0]

    track_id = results['id']
    audio_features = sp.audio_features(track_id)[0]
    
    song_data['name'] = [name]
    song_data['year'] = [year]
    song_data['explicit'] = [int(results['explicit'])]
    song_data['duration_ms'] = [results['duration_ms']]
    song_data['popularity'] = [results['popularity']]
    
    for key, value in audio_features.items():
        song_data[key] = value
    
    return pd.DataFrame(song_data)
