track not recognize by mutagen

[Etana]

hello,

with a track with no metatags, in this code models/oomusic_folder_scan.py#L484 :

# Get tags
song, song_tags = self._get_tags(os.path.join(rootdir, fn))
if not song:
    continue

song returned is a mutagen object which is falsy so the song is ignored.

thanks.
