I'm working on adding https://musicbrainz.org/release/57c5fca9-48f9-4840-96f7-3053f2ccbf71
The track list printed in the book has headers like "No. 1 in E flat, KV 16". That it's Symphony no. 1 is implied by the release title being "Complete Symphonies". Normally, I'd think then I should put in the tracks as "Symphony no. 1 in E flat, KV 16: 1. Allegro molto" (etc.).
But it also (on the first disc) has the header "KV App 223/19a in F" which I'd have to rearrange to something like "Symphony in F, KV App 223/19a" (because just plopping "Symphony" in front doesn't seem to make sense). Similarly with "KV deest in G «Neue Lambacher»" on disc 2. Which goes against having the database tell you what's actually printed on the release.
Right now I've entered the first 6 discs w/o adding "Symphony", but it looks weird. I'm thinking I should add it, and rearrange as needed.
