Hey @Dilehan! Welcome to the community!
Spotify would love to have all the music in the world but it all comes down to licensing. Sometimes artists/labels decide not to publish their music on Spotify. Thousands of albums get added every day, so keep an eye on it. In the meanwhile you can reach out to the artist and ask why his/her music isn't available on Spotify. Let me know if you have any other questions.
Take care! 🙂
