Updated request on problem with YEAR column in w4a files 2019-09-09 03:33:21 Using Default User Interface, I have a YEAR column and a DATE column (for month-day) and have entered that data to over 2,000 WAV and mp3 files. When I tried with some m4a files, I discovered that the files already had YEAR data entered, but it displayed under the DATE column when added to Playlist. I can change the data to month-day, but the Foobar YEAR column will not write data to the file. So maybe because the original file already has Year it can't take data from a Foobar column called year? So I experimented. I created a column called ANNO, and the m4a files accepted the data. Which is fine, but I don't want to go back and move the year data to a new Anno column for 2,000 mp3 and WAV files. So I wonder if I can rename my YEAR column to ANNO, without losing all the data I've entered? (It took a lot of research hours.) Because I'm nervous, I'm coming here to ask how to do that. I think I have to make a change in two places: Preferences/Playlist View/Custom Columns Year [%YEAR%] and Preferences/Advanced/Display/Properties dialog/Standard Fields Year=YEAR; The question is, which parts are changed to Anno (or ANNO)? Or is this idea not going to work? (Screen shot shows folder with m4a files and properties detail showing Year field, plus Foobar playlist view showing same m4a file Year data displaying in Date column in the top section of the playlist.)Thanks in advance for any help/advice.
