Not 100% sure as I mainly used other apps like Spotify etc, but I don't think so. My understanding is that if you have a Tidal subscription you can either use the integrated Tidal app in the BluOS system or Tidal Connect to play music. Only cost then is your subscription, not anything extra on top for using the Bluesound. FWIW Spotify integration was flawless for me (no additional cost).
