Student Discount through Facebook, Can't access Hulu

[dehs]

I've always used my spotify through facebook, so when I started paying for the student subscription, I just used the same account. I've never had any problems with this method, until I learned I can use Hulu with my student account. I tried logging in through the same facebook account, but Hulu wants me to set up my own separate subscription rather than pairing with my already existing spotify account. I'd really rather not have to create an entirely new spotify account just to get hulu to work, but if I'm already paying for both services it would be great to access them both
