@Requesting_song hey there,
when an album or song isn't added, or is removed, it's usually the choice of the artist or label - spotify wants people to enjoy an expanding library of over 30 million tracks but individual copyright decisions aren't theirs to make.
For that reason I suggest you reach out to their page or label on social media or their site!
In the meantime, you can import local files to your spotify library - you can also add your vote to this active idea!
@Requesting_song you're very welcome!
follow the links here to look more in depth about how to import local files - you'll be up and running in no time ^_^
don't hesitate to ask if there's anything else I can help with!!
