Windows only: Adam already walked you through how to download music from your friends' iTunes libraries over the internet using Mojo on the Mac, and now Windows users can get in on the fun. Install the Mojo 2.0 beta for Windows, set up an account, and swap Mojo usernames with your friends to populate your buddy list. From there you can browse their playlists, search their libraries, play and download any songs to your computer. The Mojo Windows beta is a free download; upgrade to Mojo Pro to get an unlimited buddy list. Thanks Matt and Jack!
