Release Group ID, Album Artist ID, Release Track ID, Release Type,
Status, Country, Original Date, Media, Barcode, Catalog #, ASIN,
Script, Total Discs (plus the 5 already supported). One cached API
call per album via get_release with recordings include.
New "Tags to Embed" settings section with 10 category toggles (all
enabled by default): MusicBrainz IDs, Release Info, Source IDs, ISRC,
BPM, Mood & Style, Copyright & Label, Genre Merging, URLs, Quality.
Each shows inline description of what it includes.
