Albums missing although premium subscription

[MetalMusic]

Plan

Premium by giftcard

Issue:

Why has some of the artists albums been left out? A quick estimate I would say in 4 out of 10 cases. 

Not one song either. As much as 30-50% of an artists whole catalog. 
Legal matters and copyright makes no sense to me.
Same record label, songwriters (the band) and management.

Hey @MetalMusic, 

Thanks for searching for the answer you need here!

If you can't find certain albums on Spotify it's possible the content isn't currently available in your region. Availability can vary over time and between countries and fully depends on agreements between Spotify and rights holders, such as artists or record labels.

We add new content to Spotify every day, so if you can’t find these albums right now, they may still appear soon. Alternatively, you can always contact the artist or record label with your query or make use of the local files feature.

Hope this helps. Let us know if you have any questions.
