New to mp3tag, as of today. I'm using it to convert ReplayGain tags to ITunNorm (Soundcheck) tags, using a custom action found here on the forum. It seems to be working so far. But mp3tag is also making other changes - it's adding ID3v1 tags, deleting TXXX Style tags when there are multiples, and possibly some other stuff.
Is there some combination of options that dictates, "Don't change anything, except what I explicitly edit" ? My collection is large and the tags have not been standardized, and I don't want to make any global changes now, since I don't have time to weed through and make individual decisions. All I want to do is add ITunNorm tags, and leave everything else as-is.
Turning off all three boxes under Tags->Mpeg->Remove, and turning off ID3v1 under Read and Write is close... but it still seems to mess with TXXX Style tags. (Which I guess is correct for ID3v2.3, but it's still losing information, and again, I'd like to just avoid changes rather than having to exhaustively hunt down everything that's being changed.)
