Cómo obtener los géneros de las canciones utilizando la API de Spotify.

Estoy tratando de crear un conjunto de datos de todas mis pistas guardadas en Spotify con sus metadatos. He obtenido todas las características de las canciones, el nombre de la pista y el ID de la pista. Quiero agregar una columna del artista de la pista y otra del género.

Intenté agregarlo con “liked_tracks.extend”, pero no pude hacer que funcionara.

cid = ""
secret = ""
redirect_uri = 'http://localhost:8000/callback'

FEATURE_KEYS = ['danceability', 'energy', 'key', 'loudness', 'mode', 'speechiness', 'acousticness', 'instrumentalness', 'liveness', 'valence', 'tempo']

OFFSET = 0
SAVED_TRACKS_LIMIT = 50
FEATURE_LIMIT = 100

sp = spotipy.Spotify(auth_manager=SpotifyOAuth(client_id=cid,
                                               client_secret=secret,
                                               redirect_uri=redirect_uri,
                                               scope="user-library-read"))

liked_tracks = list()
print(liked_tracks)

while(True):
    paged_tracks = sp.current_user_saved_tracks(offset=OFFSET, limit=SAVED_TRACKS_LIMIT)
    liked_tracks.extend([{'name': el['track']['name'], 'id': el['track']['id']} for el in paged_tracks['items']])
    print(f'Fetched {len(liked_tracks)} tracks')
    OFFSET += SAVED_TRACKS_LIMIT
    if paged_tracks['next'] is None:
        break

def get_windowed_track_ids(liked_tracks, limit):
    for i in range(0, len(liked_tracks), limit):
        track_window = liked_tracks[i:i + limit]
        yield track_window, [t['id'] for t in track_window]

track_feature_list = list()
print('')

for track_window, track_window_ids in get_windowed_track_ids(liked_tracks, FEATURE_LIMIT):
    track_features = sp.audio_features(tracks=track_window_ids)
    for index, track in enumerate(track_window):
        track.update({k: v for k, v in track_features[index].items() if k in FEATURE_KEYS})
        track_feature_list.append(track)
    print(f'Fetched features for {len(track_feature_list)} tracks')

df = pd.DataFrame.from_dict(track_feature_list)
mysavedsongs = f'liked_tracks{int(time())}.csv'
df.to_csv(mysavedsongs, index=False)
print('')
print(f'Saved features to {mysavedsongs}')
