No, just the explicit steps that I wrote

Cerainly could be.

But I am a pure black-box tester - I don't do that white-box under-the-hood look at the code stuff ;)

@cjsmall - I have logged your original issue as P3 Enhancement Bug #2802
https://bugzilla.audacityteam.org/show_bug.cgi?id=2802
Bug 2802 - ENH: Metadata custom entries are ignored by Audacity on export

Thanks for the report.


---------------------------------------------------------------------------------------------

I also added P2 Bug #2801 as a result of further testing today
>Bug 2801 - Metadata: most metadata is discarded on import into Audacity (and subsequent export from Audacity)
https://bugzilla.audacityteam.org/show_bug.cgi?id=2801

In relation to this 2810, longstanding (7 years) Bug #701 also applies
https://bugzilla.audacityteam.org/show_bug.cgi?id=701
Bug 701 - Metadata: Embedded album art and lyrics metadata discarded

Audacity uses ID3 v2.3 tags for MP3, and has read/write support for:
  • Artist Name
  • Track Title
  • Album Title
  • Track Number
  • Year
  • Genre
  • Comments
  • <custom>
There may be multiple "<custom>" fields, though they may not be supported by other apps.

If an MP3 contains only ID3 v1.x tags, Audacity will import:
  • Track Title
  • Album Title
  • Track Number
  • Genre
  • Comments
Audacity does not write ID3 v1.x tags.
