HI!!!
I had a somewhat peculiar idea.
I have many collections in my library that contain the same song but on different files in each collection.
If the MB could have multi album so that the same file can be shared by multiple collections so as to save space in bytes.
Example: the same song appears in 7 collections, the single song occupies 4 MB but multiplying it by 7 becomes 280 MB, with the multi album you could save 276 MB.
By author there is often the best, the greatest, the monographic, the period like the 70s plus the collections of various artists that contain the song of an author whose discography you already have.
I don't know how easy it is to script this but it would be so useful, in my opinion.
The multi-album
