I received a gift card to Hulu for Christmas. I am far more interested in Spotify than Hulu so I was excited when I found out about the Hulu/Spotify partnership. Does anyone know if there is any way that I can have my billing go through Hulu for the Hulu with Spotify so that I can use the gift card? Or does it need to go through Spotify? I don't have a Spotify gift card to use.
