My Question or Issue
What ID3 tag is used for Albums for local files in Spotify? Typically one would assume TALB as per the standard but after having experimented a bit it seems like Spotify isn't referring to which Album the song is from despite the MP3's "Album" tag being populated?

As it is possible I have misunderstood something I would really appreciate any direction in how I would approach the problem of correctly adding the appropriate meta data to all MP3's in such a way that Spotify recognizes the information.

Thank you ahead of time!
