Strip ID3v1 tags and iTunes Specific Comments Field

[Joel Verhagen]

Is there an easy way to completely remove the ID3v1 section from an MPEG
file? I will be adjusting the ID3v2 tags and I don't want to have to keep
the ID3v1 tags up to date, so I would like to just strip them out. FYI, I am
using C++. This is my current code, just to give an idea of what I have thus
far: http://paste2.org/p/1070301.

Also, I seems like TagLib is missing a little bit of data from the ID3 tags
of MP3 files encoded in iTunes. I opened an MP3 I have in my iTunes library
up in a piece of software called Mp3tag (http://www.mp3tag.de/en/).

My program's output about the comment fields in my test MP3:

In Mp3tag, all five of those comment fields come up, but they have longer
keys, i.e. the five keys are COMMENT, COMMENT ITUNES_CDDB_IDS, COMMENT
ITUNNORM, COMMENT ITUNNORM (another), COMMENT ITUNSMPB. This says to me that
there is additional information in the ID3 that TagLib is not getting but
this freeware Mp3tag _is_ getting.

Is this a bug? Or am I missing something?
