In the past I was able to, but ImportMP3.cpp now has tag code commented out.
I tried adding the following to MP3ImportFileHandle::Import():
AudacityProject* *pProject = gAudioIO->GetProject();
Tags *tags = pProject->GetTags();
but pProject is NULL. Doesn't the project exist when
MP3ImportFileHandle::Import() is invoked?
(I didn't show all the changes I made, only the pertinent lines.)
