We stumbled across this one in the CrackBerry forums earlier and couldn't help but pass it along.

As you may or may not know, BBM has an option to share what music you listen to in the media player as your status update. This feature is disabled by default but if you happened to toggle it on at some point, it can of course be disabled if you know where to look.

As it turns out it's a good idea to disable it if you plan to share anything other than what music you're listening to.
