> ID3v2.3 or IDv2.4? Can you even do that to FLAC? And where do you get that metadata, using what tools?
I rip my CDs to Ogg Vorbis, so the ID3 question is moot. Yes, FLAC supports plenty of metadata. I use beets[1] for tagging, which uses MusicBrainz as the source of truth.
> exactly what metadata do you want outside of artist, song title, album title?
Album Artist, and sort-orders for albums/artists what I like the most (but not all players use those), then yes album covers are useful. I don't really care about subgeneres, but there is a plugin for beets that will fetch those from last.fm
