Questions about Classical tracks?

I am adding image files to some albums and I found that some of the track names are incorrect. I’m scared to edit the tracks because classical tracks/recordings seem so complicated. Could someone take a look and/or guide me on how to fix these respective tracks?

  • Mozart: Musical Masterpieces - Tracklist img
    • Track: “2. Concerto for Clarinet in A major, K. 622: I. Allegro” (Should be - “2. Concerto for Clarinet in B flat major, K. 622: I. Allegro”)
  • Brahms: Romantic Passions - Tracklist img
    • Track: "4. Double Concerto in A minor, op. 102: 4th mvmt (Should be - “4. Double Concerto in A minor, op. 102: 2nd mvmt”) - I tried editing this and stopped because it looked odd

Edit:

  • For the Mozart piece, I went with @Beckfield’s suggestion. There was a precedent I found in the German edition of the release.
  • I edited to match the tracklists and expanded the "mvmt"s per @Beckfield again. I expanded in my edit notes.

It’s generally best to make the track titles on the Medium match what’s on the artwork, but Recordings should be more of a “standard” form, like the ones associated with the releases you linked. More about Recording Titles for classical music here.

If you are certain that the images you are adding are the correct ones for the release, I would proceed as follows:

Edit the track titles on the Medium to match what the cover art says, but apply MB’s Classical Style Guidelines (“major” or “minor” not capitalized, “B-flat” instead of “B Flat” etc.).

Do not allow the track titles you’ve entered to be copied to the Recordings (unless, as I see in one of your edits where the movement number is wrong, there is an error in the Recording title).

It seems that Mozart’s K622 is in A major, not B-flat major, so this is most likely a typo in the cover art which has been corrected in the MusicBrianz tracklist. I would leave it alone. Maybe add an annotation.
