Yes it's what i want to do, because i have made a script Shell which : 1. record a extract of a song (10sec) that is currently played on my computer, and 2. call a python module to search the lyrics that correspond to this song (that's why i have to use track.track_from_filename(mp3)).
And the problem comes from s.get_tracks('musixmatch-WW') which always return an empty list, although i succeed in find the song_id of the track...
