I agree, I also have a premium account and I dont think I should have to wait along with regular users for the same release. Because we pay the most we should have First access to new releases and well before the general spotify public.
How come there are no explanation on Spotify as to why we can't play the album/songs? It's just says "This album is unavailable". And how come Diamonds were available and then removed? There might be a perfectly reasonable explanation for this, but why shouldn't we be informed why we're not getting what we're paying for?
However, I don't see how it related to this issue. Both Rihanna and her label are a part of Spotify.
I think the main point here is how Spotify handles new releases. Although the album is for sale on services like iTunes, we are not able to listen to it despite the fact that we are paying to listen to these songs. In fact, we are paying over and over again to keep listening to the music. How is it different to pay monthly to listen to a track/an album compared to paying a one time fee and then have the files locally on your computer? How long does Spotify users have to wait to listen to new releases when it's available for purchase elsewhere? I don't see the point of buying an album I will be able to listen to via Spotify later on. But how long is this supposed to take?
