I have used a number of updated versions of AAC files will often cause damage.  
If iTunes Plus AAC m4a Tag album edited and re-saved,  
Occurs 1-2 song does not play.  
Not every time this happens, but have encountered many times.  
Has anyone had this before?

p.s. mp3tag 2.57, Windows 7 OS

Where do you see MP3tag's role in this scenario? I only read iTunes and a certain codec. As MP3tag does not encode files I do not see the relation. Or is this more an off-topic?
