Hi @jan van der vliet 

We're really sorry to know the tracks you love isn't on Deezer. Not all artists and rights' holders choose to add their music on our platform. We always respect their wishes so some music isn't available or might be temporarily removed. 
 

Hi Jan,

Just like @Nina Nebo said, it all depends on the artist or the record company.

This instrumental album is nowhere to be found. So it’s not only Deezer, but also others.
