Feature description

I would like the Music Player to notice when the same track appears multiple times (identical metadata, length) and hide the duplicates when appropiate such as "all tracks" listing or album view.

Why do you want this feature?

My music collection includes digital albums that contain MP3 and FLAC subdirectories that occassionally both find their way to my phone. I also have devices that only support MP3, so I cannot entirely get rid of those files (in favour of flac or even opus) and thus regularly have to convert to mp3.

Additional information

Hiding duplicates would require Music Player to consider which is the canonical track and I would like that to be the best quality possible, possibly in order flac > opus > ogg > mp3. However since there are so many audio formats (and I understand the format support comes from Android OS itself?), I think the duplicate hiding or preferred format order may have to be an option if this is even in scope for the project.
