Planetary is a new iPad app that visualizes your music collection as planetary systems. It’s VERY cool, and free. So it’s worth a look just to see what the fuss is all about. Although I can’t say it’s a great way to navigate and play your music, it’s definitely something you want to use to show off when your around other people. So download it and keep it on your iPad, the wow factor along is worth keeping it around. If you want an actual review, check out Engadget’s, they even made a video.
