Hello,
I'm lost. To retag correctly my mp3, I have used mp3tag, but I'm not a god and I must have done a mistake : all my mp3 are now m4a ! And I can't hear them now on my computer and my ipod. May someone help me and explain how to change them back in mp3 ??
Thanx in advance,
Marc
Hi Marc,
I doubt that Mp3tag changes the file extension from mp3 to m4a, but you can always try to change the file extension back to mp3.
If this doesn't help you, you can send me one file to my support email address.
Best regards,

Hi Marc,
the file you've sent to me is not a mp3 file but an Advanced Audio Coding (aac) file. This was definitely not changed by Mp3tag, because Mp3tag hasn't any transcoding capabilities.
I've played the file with iTunes and with foobar2000 and both worked quite well.
Best regards,

THankx Florian for your answer. I have finally find the problem : the format of encoding in itunes... and the more idiot : itunes doesn't "see" automatically the files in itunes music file... your must drop them !! 
I learn everyday !
