[music player] Use "Album Artist" tag to avoid multiple artist entries for compilations

• /e/ version: 2.7
• Device model(s): xz2c

Maybe updating the music player from LineageOS' discontinued Eleven to currently maintained Twelve would fix this issue and others ?

Summary

Albums that contain tracks by several different artists are not properly grouped under the given Album Artist tag.

Description

Even when properly tagging my files/tracks using the Album Artist ID3v2 tag, several single albums by Various Artists are displayed in the Artist view as separate albums by so many artists.

What is the improved behavior?

Single albums containing several tracks by different artists should all be grouped under the same Various Artists label, or whatever is the value of the Album Artist (i.e. main artist) tag.

What does it bring?

I have about 800 music albums in my library, and growing. Several of them are compilations or personal track selections containing tracks by multiple various artists. At the moment I cannot select one artist/album to play on the go. Using the Albums tab has too many entries to do this.

Examples

Find a compilation album through the Various Artists grouping or through the main Album Artist entry.

Validation

Use any album that has different Artist tags for different tracks but the same Album Artist tag for all tracks. See if it is correctly displayed under the same Artist / Various Artists in the Artist tab.
