Extending Lyrion's use of tag metadata to enhance ways in which users can browse /interact with their music via Lyrion

[audiomuze]

A lot of progress has been made in Lyrion over recent years to better leverage tag metadata and thereby enhance a user's ability to interact with their music. Combined with Material Skin, Lyrion presents a compelling UI/UX, but there is room for further improvement.

This discussion thread is intended to solicit input from users as to what tag metadata they would like to see Lyrion support and why. The hope is that it serves as a valuable input to developers in deciding how far to go and what should be prioritised.

What follows are tags I'm aware of in my own music metadata, some of which may be useful:

🎵 Core Metadata Tags

• ✅discnumber – Disc number in a multi-disc set.
• ✅track – Track number on the disc.
• ✅title – Main name of the track.

• ✅composer – Original composer of the music.

Enables Lyrion to stop conflating different releases of same album without relying on some mbid identifier.

Meaning
✅ = ingested by Lyrion
❓ = not sure if ingested by Lyrion
❌ = not ingested by Lyrion

❌✅ = should be but isn't at present
✅❓ = should be but not sure whether or not it is
❓❓ = unsure whether it is and unsure whether it would serve a purpose

I'd be happy to elaborate on why some might or might not be useful to me, but I'd like to hear from others that find metadata useful to how they explore and interact with their music.

Thoughts from others?

I'm surprised I'd have to tell you, but you'll reach a much wider audience in the forum. I doubt that besides @darrell-k and myself anyone would come here.

Where would you want it posted: Lyrion Music Server (LMS), Beta or elsewhere on forum?

Ripping/Tagging or General LMS?

On the "People" category, they (and anything else) can be added using user-defined roles, which should then be treated no different to the built-in non-Artist.AlbumArtist roles. If we do find functionality differences, that's what needs fixing.
