import os
from gtagger import gTagger

# your Genius API token
token = '...'

# path containing music
source = '~/Music'

# instantiate the tagger by providing
# token and an optional logger
gt = gTagger(token, print)

for filename in os.listdir(source):
    path = os.path.join(source, filename)

    # tag the file by providing
    # a query (filename) for matching
    # and the path to the file
    gt.tag(filename, path)
    
    # additionally the tag method also takes a genius_url
    # parameter for directly tagging instead of inferring from filename
