I missed that article. Do you have links to such expert information that pours acid on taggers that add information to flac files?
I use Media Rage to add tags to different types of files.
Media Rage
I could just as easily go back to using Apple Lossless. Just limits who can use them. If FLAC is so affected by tags, then it was definitely a mistake to start using FLAC. It shows FLAC's limitations compared to Apple Lossless that players or burners should be affected by such minor issues as tag information.
iTunes cannot play FLAC for example which is my main player.
