First of all: Florian, thank you very much for this nice and useful program.
I have the following problem:
I have re-mastered my tagged original MP3-/WMA-files with Magix Music Cleaning Lab. After having done that all ID3 Tags are lost.
With MP3tag it was easy to copy all ID3 Tags from the original files to the re-mastered files and these Tags are then shown correctly in MP3tag and in the MP3-/WMA-file properties. But when playing them in Windows Media Player (newest version) these copied Tags are not shown although the Tags of the original files are shown there correctly.
