iTunes 4 best, and quite overlooked feature, is Sharing. If you go into the preferences you can turn sharing on, and your friends can connect to your iTunes and stream any song in your library to their mac! This beats the old standbye of streamed radio stations hands down because you can select any song you want to listen to instead of listening to whatever song your friend wants to push to you. What I want to know is how long before there's a (preferably linux) iTunes server software? I want to be able to upload all my mp3s onto a dedicated server and then my friends and i can listen to my music from anywhere! I wonder if I bought an Xserve if it will run itunes... joe.
