Not sure how many people have this already, but I just discovered this awesome app for Mac users. It allows you to listen to Pandora on an actual desktop window (which means you get a growl notification with the song/artist when the song changes). Even better than that, it can record everything you listen to and automatically put it in iTunes with the right artwork and tags. Just figured there would be a few people in M&A who would appreciate this. Here's the link:
