We are trying to convert songs (MP3/AAC) using separate delivery, but the songs information (like the artist, title, etc) is missing in the 'Gallery' application. I was test it on n6630 and n6680, both phones can not displayed the information correctly. I also already tried to transfer the mp3/aac file before it converted to dcf file, and the informations is displayed.

Do you know what is the problem ? Or is there any tool/applications to convert the mp3/aac which keep the songs information ?
