Just ran across this streaming music service, 8tracks.  They have playlists of selected music by topic.  One is zydeco currently there are 27 playlists available.  Fortunately, there’s a lot of good listening here.  Unfortunately, there is some confusion about what zydeco is, with lots of Cajun and other music mixed in.   No sign up required to listen.  Title, artist, album, and links to iTunes and YouTube are provided.
