You can access any ID3 frame present in the file, but to do so you
need to use the TagLib::MPEG::File and TagLib::ID3v2::Tag classes.
For example (typed in Mail):
TagLib::MPEG::File f(filename, false);
TagLib::ID3v2::Tag *id3v2tag = f.ID3v2Tag();
TagLib::ID3v2::FrameList frameList = id3v2tag->frameListMap()
std::cout << "Composer: " << frameList.front()-
>toString().toCString(true) << std::endl;
