iOS-Spotify premium app for free users

[user-removed]

Hi,

I am going to develop an iOS Spotify app for my Master's project. As a student developer in the Netherlands, I understand that there is no student discount available (yet) for Dutch students. In any case, here's my question:

- If I develop an iOS app using the iOS Spotify SDK (for which I will need to get a premium account), can only premium account holders use that application?

- The app's goal is to develop a music recommendation system - so there will be a next track option made available to user's. Will the next track option be disabled for free users until an ad is played or how does that work?

Cheers,

Abhishek.
