There was a patch to add sort order tag support to the Database a while back, possibly (probably?) the one you were looking at.
I recall there was some issues with how it was originally implemented. If my memory serves me correctly it was basically using albumsort instead of albumartist, instead of sorting by albumsort and displaying albumartist...but I don't recall if this issue was ever addressed.
Even if it was, it wasn't committed - so to use it you would need to commit to always compiling your own builds and using an unsupported build forever more. There is however, depending on how determined you are, a way that one could achieve similar functionality with a custom
tagnavi file and (ab)using the "comment" metadata field.
The way I'm thinking it could be done is by slightly changing the tagnavi file so that "Album Artist" displays the "Comment" metadata field instead, or perhaps adding an entirely separate entry, its up to you.
But this wouldn't behave quite as one would expect it to. Instead of:
A
The Beatles
C
D
It would be something like:
A
Beatles, The
C
D
etc.
But in the while playing screen (unless you edited that too...) it would still use the existing Artist/Album Artist tags. Just a thought. Let me know how you get on, I shall have a think about this further, and maybe we can bounce ideas off each other and come up with something that suits you.
