Thanks for posting in the Spotify Community, and I hope you don’t mind me replying in English.
Availability of music can vary over time and between countries, depending on agreements between Spotify and rights holders, such as artists and record labels; therefore, content sometimes isn't available right away. Spotify works to adds new content to the platform every day, as and when it is made available to Spotify; hopefully your favorite music will be up soon.
In the meantime, you can import local files to your Spotify library if you have this music as files on your computer.
Let me know if you have any other questions, and have a good day!
