Claudio, is it possible that you can give me just the ID3 portions of the file,
and not the copyrighted music portion?

I'll need both the ID3v2 and ID3v1 tags. ID3v2 is at the start of the file,
ID3v1 is at the end. You can determine the size of the ID3v2 tag with a command
like:

GST_DEBUG=id3demux:5 gst-launch filesrc location=/path/to/file.mp3 ! id3demux !
fakesink 2>&1 | grep ID3v2

and look for a line like:
DEBUG (0x80509d8 - 0:00:00.430592000)             id3demux(20778)
gstid3demux.c(736):gst_id3demux_read_id3v2:<id3demux0> Read ID3v2 tag of size
149

You can then extract that many bytes from the start of the file:
dd if=/path/to/file.mp3 bs=1 count=NUMBER_OF_BYTES of=/path/to/id3v2.tag

Extracting the ID3v1 tag is almost as easy. ID3v1 tags are always 128 bytes and
must always be at the end of the file. So, you want to compute the starting
byte  as OFFSET=(size of the file - 128) and then run:
dd if=/path/to/file.mp3 bs=1 skip=OFFSET count=128 of=/path/to/id3v1.tag

Attach those for me, and I can have a look at the genre information.
