Hi @beka,
I’m writing to report the results of some hacking that may be of interest to any developer looking at this problem.
Wondering if there might be some unwitting implicit requirement in Roon to only allow the replacement of synchronized lyrics with synchronized lyrics and using the same track that supplied the screenshots in 162884/8, I added a spurious timestamp to the the source file’s LYRICS tag: “[00:00.00] Test”. Here’s the screenshot of the lyrics tab with the track in play that resulted:
So it seems that for me, at least, Roon will only replace synchronized lyrics with synchronized lyrics. That does not seem to be the case for @Rugby, though he indicated that his results varied depending on core platform, without saying exactly how.
& unfortunately, there’s more … Here is a screenshot of what happens when I do a right-click “View Lyrics” from the screen captured above:
This shows the unreplaced cloud-sourced version of the lyrics, so all I’ve really done with this hack is to change the way in which Roon is ignoring my LYRICS tag.
