”Spotify can’t play this right now. If you have the file on your computer you can import it.”
Once, long ago, I used to have a certain album on my computer – I had bought the album from iTunes. Once, long ago, I used to have Spotify linked with my iTunes. Now, I no longer have the album on my iTunes, nor do I want Spotify to search for it or link a none-existing file to my player.
I can find the album on Spotify and have Spotify play it on my mobile devices. I also find it when using Spotify on my computer, but Spotify won't play the album, and is stating the quotation above. (From the Spotify web player I can find and play the album.)

I've checked Preferences: Local Files,
and all (iTunes, Downloads & My Music) are turned off.

I removed the desktop app & the cache-folder from the library and installed it again. Still not playing the album.

What should I try now? 🙂
