[COLOR=Black]It’s possible to get data out of an MP3 file. I added the code and tested, but nothing is appearing in my output panel. I’ve tried several MP3 files and nothing appears. These same MP3 files are in my iTunes library and I can see the data if I got to Get Info.

I’m doing all of this on a Mac. What could be the problem? [/COLOR]
