I have successfully edited MP3 tags without trouble, however when I edit FLAC files using the same procedures I am having problems. I would like to put album art in individual FLAC files. I am making a compilation disk and would like for each song to display the album art that the song was ripped from. I start by removing the tag (clicking on the red x) and input the correct information and album art, I am sure to save each file when I am finished. While still in the Mp3tag program and everything displays fine as I scroll to each file, but when I play the FlAC file in Media player the unedited tag information is still being displayed. I am sure that I saved after every edit. As I said before if I use a mp3 file it works beautifully. . . . not so much for a FLAC file.
