wow! i must say that iTunes 4 definitely rocks! itunes 3? what was that? This music streaming feature is so awesome. When i first launched iTunes4 today and turned on music sharing, i had 3 people already connecting!! AND, the coolest part is that your friend half way around the world can even connect and stream ur music?!?! kick ass or what? If you wanna see and listen to my collection, catch me when i'm online. (AIM: chibianh). I hardly ever post but i'm too excited with this feature! btw, open port 3689 on your router for iTunes.
