Ignore duplicated files when playing album

[rndeon 0]

I have music libraries on my server, and some songs are duplicated between them. When I play an album, I have not found any way to get emby to play the album as intended, only playing (for example) a single instance of track 3. It always runs through all of them.
Some ideas that might solve my problem, if they exist. Do you know if I can do any of these?
- in the android app, start playing an album but have filtered to only one music library

- change emby's album-playing logic so it only plays the first instance of any duplicated tracks

-change the file scanning logic so it won't include fully duplicated files, even across two library folders. This one's a bit tricky, because of course covers, or multiple versions...it would have to be identical metadata to trigger skipping, I guess.

Anyone got a potential solution?
