Share any song in your iTunes library and download any song from your friends' iTunes libraries over the internet with freeware application Mojo.
o get started, you need to download and install Mojo on your computer (it's fully ready to go on Macs, and currently in beta for Windows). The first time you run Mojo, you'll be asked to create an account. Do that, then you'll see the Mojo friends window, which is much like a buddy window on an instant messenger client. Granted, you won't have any buddies in this window to begin with (unless it's also been installed by another computer on your local network), but don't worry, you will.
Next, let's say your friend downloads and installs Mojo as well. They give you their user name, you hit the little plus (+) sign to add them as a buddy, and they're sent an approval request. They approve you, and voilà—you now have access to every song in their iTunes library.
