Thanks for searching for the answer you need here!
We appreciate you taking the time to share your suggestion with the Community. Spotify works hard to constantly add music to its content database. We want all the world’s music and podcasts on Spotify, but availability can vary over time and between countries, depending 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 something you’re looking for right now, it may appear (or reappear) soon. You can also contact the artist or record label holding the rights over the album you wish to be added. They can help you with more info regarding availability of the artist on different platforms.
Hope this helps. Let us know if you have any more questions.
