itunes Shared Music?

[NinaPooh]

Hi all, I've have my ibook for a about 6 months now, and I just recently started buying music from itunes because I have access to ethernet access provided by my college. Anyways, I was messing with it today and clicked on Shared music. There was like three different people's play list with lots of songs that I was able to listen to? I'm confused as to where all this came from and most importantly, will it cost me anything?

Welcome to the wonderful world of Rendezvous music sharing. iTunes automatically detects other iTunes users on the network (Your dorm's) so that you can listen to their music when they're around. All of the music is streamed, not downloaded so it's 100% legal and free!
