Hello @Awdn297 and welcome to the community, I guess you are in USA?
All the "A Day To Remember" albums are available worldwide on Spotify, except US where only 2 albums are available. All the albums not available in US are from a label called "Another Victory" or "Victory Records" based in Chicago. It seems to be a licensing problem with this label and US.
Spotify wants all the music in the world to stream. Unfortunately, sometimes, due to licensing problems or by decision of the artist or a label, some albums are not available at all on Spotify or partially available in some countries.
Spotify works hard daily to try to convince them to have all their music available to stream.
The best users can do to help is to try to contact the label and ask why the albums are not on Spotify.
