I’ve recently started using Simplify Media to share my home iTunes library so I can listen to it at work. It’s working great so far and I’m now letting all my friends know that they should install it and share with me. The application installs an IM-like client in your system tray where you add up to 30 friends. Then, in iTunes, you see all of your new friend’s libraries for you to play to your hearts content. Install it and let me know.
