Bug Report: incorrect handling of metadata
« on: October 29, 2014, 03:55:40 pm »

4 bugs to report:

"Update Library (from Tags)" does not "update", it appears to "merge" instead.

For example, deleting a Contributing Artist from a file, and selecting "Update Library (from Tags)" will result in the deleted artist remaining listed in JRiver Media Center. Expected behaviour is that JMC will reflect the actual content of the file after using this command, not some combination of what it had and what the file currently contains.

Also, deleting an album from the library and allowing JMC to reimport it persists the old metadata and does not read the new metadata from the file as expected. It appears the only way to resolve incorrect tag information is to clear the library.

Bizarre as it seems, clearing the library also resets customisations to library settings (as regards watched paths and which file types should be imported). So this item highlights 3 bugs in the library interface.

All albums are displayed as "Various Artists" regardless of what the Album Artist tag actually contains.

It appears that the Contributing Artists tag is being misinterpreted to inappropriately construct Album Artist information.

I doubt it, as "Contributing Artists" seems to be a custom tag which does not even exist in my library, and Media Center does not use "Various Artists" - it uses "(Multiple Artists)".
 
However [Album Artist (auto)] was changed a while back and now results in the majority of albums in my library being listed as (Multiple Artists)

Artist is list field so it may just be adding to the list in the database instead of overwriting it.
Kind of makes sense since you are updating tags and not re-importing. I don't know though.

You may not be completely removing the album from the library.
Items can be completely removed by making a smartlist with a rule of ~d=r and deleting the files again from there.

Keep in mind MC uses the Artist field and "Album Artist" field.
"Contributing Artists" and Artists are typically the same thing.
Just some software calls it Contributing Artists (like windows) and some call it Artist (like MC)
If your Albums aren't showing up in MC correctly, have a look at the individual files in an album and check the Artist and Album Artist fields.
It's always possible you have an issue with one of your views that causes them to display in an undesired way.

It may be useful for you to post what software you are using to edit your tags outside MC as well as what you are trying to accomplish.
Different players and tagging software use different naming conventions and typically only a small number of fields are compatible between by default.
Album, Artist, and Album Artist should not be having issues though.

Also what file types are you using? FLAC and mp3 can store all fields in the file where other file types only store some fields in the file and the rest in the database only.
