Why are tracks not available when they were previously?

Hey guys, 

I have been listening to "The family Jewels" album by Marina and the diamonds and I have noticed that the songs that were available previously (Obsessions, Hollywood and Rootless) are now not available, why is that? 

Thanks

Hey @RenaFujoshi

Sometimes agreements can’t be reached with the artist or label or a change may happen in music ownership. Spotify has to honour this and make the songs unavailable until its fixed. Keep checking, they may reappear soon.
In the meantime, feel free to contact the artist or their label to ask when they plan to be on Spotify.

Thanks!
