[FEATURE REQUEST] Automatically generate Album Artist from Artist tags if Album Artist tags are empty

[Immabed]

Is your feature request related to a problem? Please describe.
Some of my music is in albums, usually with a single artist, but doesn't have the Album Artist tag populated. In these cases when scrolling through the browse albums view, the album doesn't display the Artist's name. Also when looking at a single album, the artist is not named under the album name. This is a minor thing, but I do like to see the artist name for each album, when applicable.

Describe the solution you'd like
The minimum feature would be to, when an album consists of songs exclusively by a single artist and every song in the album lacks a tagged Album Artist, the app displays the artist's name as though it was the album artist. I'm not looking to actually change the tags in the songs, but simply to display the Artist's name as though the songs were tagged.

In the case of albums with more than one artist, but where still no album artist is tagged, the various artists could be combined into a list (ordered by number of songs by the artist in that album).

This feature could be a toggle-able setting.

Describe alternatives you've considered
Alternatively, for albums with more than artist and no album artist tagged, the app could simply display 'Various Artists' where the album artist would be displayed.

It could be possible to mass alter tags to actually populate the Album Artist tags in these unpopulated albums, but I fear that could be problematic, for instance if multiple albums of the same name were combined in the app because a user didn't enable additional album identifiers.

Additional context
Note how the Nidhogg album has no Album Artist in either view, despite only having music from a single artist.

I would blame my own music tagging, but many of my albums are directly from digital marketplaces so the issue of missing Album Artists affects more than just home-tagged music, which is why I think an in-app solution is preferable to re-tagging manually.

I would say that the 'Extract feat. artists from title' is a similar type of feature, although this has the added complication of operating on entire albums instead of individual songs.

im more worried about the performance cost, since this can't be done while indexing/etc and would require calculations in the ui itself, for example u would need to check all tracks inside while scrolling
a separate option just for this sounds like an overkill

im exactly like you, but idk i dont think auto showing that is a good idea, despite performance u would see album artist for an album that is not officially labeled so, which could be misleading

another option is to tag 1 track only album artist, would then show normally

update: i actually tried this and it looks kinda cool

for performance, we already try to get the first non-empty album artist, i realized that if an album has no album artist at all, it would still check all tracks to try get that album artist, if not found then just show the cumulative artist we been collecting on the way

thanks for the suggestion

will try more and update u soon
