Customers in the US can now take advantage of a sweet offer from Spotify - a free Hulu subscription with each premium account. And the good news is that it's not for new customers only. If you are a current Spotify Premium member, just go to "Your Services" page on Spotify's website and activate your free Hulu subscription. However, the offer won't last forever - it will be available until June 10 so make sure to claim what's yours and catch up on those Hulu original shows and other movies and TV series. Source
