Album sort order

Hi all, absolutely loving Volumio thankyou!

Would like to confirm if all album folders (CIFS NAS) must be in alphabetical order by artist (within same mapped parent folder)…

I notice even after painstakingly correcting albumartist of my 3000+ albums, many continue to sort by folder order…seems to undermine the point of sort by albumartist if I also must rename the file system for same no?

Many thanks!
