Moving one tag field into a different tag field

I've been trying for hours to figure out how this works. I am thinking of %UNSYNCEDLYRICS% field and all it's contents to the %LYRICS% field. Can anybody help me figure this out? I have decided to use the %LYRICS% field now since I have found a way to retrieve synced lyrics for my music files.

Thank you in advance for whoever is kind enough to help me out!

You could start with this:

or just directly to swap the content

To move UNSYNCEDLYRICS to LYRICS and remove UNSYNCEDLYRICS use an action of the type "Guess value"
Source string: ==%unsyncedlyrics%
Target format string: %unsyncedlyrics%==%lyrics%

Thank you so much. The second suggestion worked flawlessly like what I had in mind. I appreciate it!

this also works! thank you.

Just a side note:
Please be aware that your LYRICS tag is a user-defined field.
You would have to check if your players can read the content of this field.

The official two lyrics tags for MP3 files are
UNSYNCEDLYRICS
and
SYLT

SYLT is the one with the time-stamps in front of the text lines.

I missed to point out that all of these are for FLAC files. I hardly have any MP3 files in my music library. Thank you for that information though. If you have any insight with FLAC files and what lyrics tag standards they use, that should help me a lot too. I just started building my library and I am new to this.

You would have to test which field your player accepts to display the (synchronized) lyrics.
For all other player use the lyrics without time codes.
It should be possible to have both tag fields in the same file.

FLAC tags are loosely structured. You can read more about them here:

Supposedly both the Poweramp and Musicolet players support FLAC synchronized lyrics. There may well be others,
