Thanks,

I think maybe you misunderstand me, I mean whether the situation could
happen, the MP3 music media data(not the Tag frame data) start with
"ID3", but this "ID3" is not the ID3v2 Tag's identifier.

In fact the MP3 file without ID3v2 Tags, only ID3v1 exist.

do you think this situation would like happen.

thank u again...
