My music has ID3 version 2.3 tags (most common). About 10% (2,500) of my music is AAC (.m4a) format which is MP4 tagged. All my songs are very organized into 11 different genres. Everything has a title, artist, and album assigned to it and looks great in my iPhone, iTunes, MediaMonkey, and Mp3tag program. When I add my music to my Samsung Fascinate, it reads the tags of my .m4a music but when I go to genre, things are messy. It appears to be putting albums in the genre section (only with .m4a files). Example: Lets say I have an .m4a of Garth Brooks, Thunder Rolls, No Fences (album), Country (genre) In my Samsung Fascinate player, it will be found in the genre section under "No Fences". If I click "Country" genre where it should be, the song will not be listed there. It seems to be reading .m4a Album tags as genre and not reading the appropriate tag "Country". I hope someone can help straighten this out without having either manually edit each song tag OR convert all of them to .mp3 and deplete the song quality.
