Hello What I want to do is to be able to tag song name and artists or different sections of a lecture or interview inside one mp3. Is it possible within iTunes? From what I have found it is only possible to tag a mp3 once, not adding metadata along the time line, I would like to be wrong obviously. If there is a third party application available to do the same thing I'd like to know as well. Cheers Ok, I'll add this bit too. I would also like to jump to these sections as if they were separate files as a way to avoid fast forwarding. I know I can cut the mp3 up, but I have seen it done with one file.
