Was it only a year or two ago that we posted instructions on how to add "what's playing" notifications to iTunes? These days, we're fielding requests on how to turn the darn notifications off.
Yesterday, our own Ilene H was haunting the TUAW back channel trying to figure out how to de-Mavericks her iTunes, so they wouldn't keep popping up as she was working.
Fortunately for Ilene and other iTunes users, there's an easy fix. Just hop into iTunes and navigate to Preferences > General. In the Notifications section, uncheck the "When song changes" box and bob's your uncle. Those iTunes updates will stop popping up and you can get on with your work.
