If I add a User defined tag input field that corresponds to a defined frame in id3 v2.3.0 does the data I put in the window go into that frame?
Suppose I define a user field "Conductor". Put in some data e.g. 'Zubin Mehta'. Write the whole tag to an .mp3 file. Does MP3TAG put that data in the "TPE3" frame (TPE3 is the frame designated for conductor according to the id3 v2.3.0 standard) when it writes to the file or does it put it somewhere else?
