Whooshkaa has a direct integration with Spotify, meaning that your show is only moments away from being Spotify too!
To submit, log in as the show owner, go to your show's Overview page and click on the "Submit to Spotify" button. Review the terms and conditions and if you agree, hit "Submit". That's all there is to it.
The show will then be submitted and be available on Spotify within the next 24 hours (usually much faster than this).
