The album in question is a Grigory Sokolov recording of Schubert (and Beethoven). The second work on disk 1 is listed using (apparently) the Allmusic working title, as show in the screen shot:
.I’m being a bit pedantic, but Schubert wrote just two works titled “Impromptus” and this isn’t one of them. It should be just “3 Pieces”, or better, “Drei Klavierstucke”. So the first question is, can I change this, and if so, how?
Secondly, I’d like to remove the word “Impromptu” from the individual tracks. I’ve tried with the track editor, and nothing happens. Here’s the track editor screen shot::
I can select either one and click “save” and nothing happens. What should I have done instead? I note that I can readily change track titles on the second disk of this set, at least where the tracks are not part of a larger work.
