Hello, @yougoz94! This album seem to be available from Poland. Where are you from? Are any other Eminem albums available on Spotify for you? There are two possibilities as to why the album you mentioned isn't available:
1. It's down to the record label in that they may have limited which regions would have access to the full album. In this case Spotify can't really do much about it.
2. It's a temporary issue. No need to worry as the album should be back in no time.
