Odd thing happen to me. I hooked my powerbook up to the schools internet access line by way of ethernet (proper technical terms allude me at the moment) and opened up itunes. On the source side of itunes where your library is at someone elses music library should up along with mine. I was like WTF??? After a few seconds thinking about it and knowing about the guy whos music library showed up in my source area because it was titled with his name (and I know hes the only other guy in my university who as a powerbook and uses it at school and has that type of "trendie mtv music") I knew exactly what was going on. I was shocked. I didnt know macs had this capability. Impressive. Sorry this is probably common knowledge to you guys but its wasnt to me. So if I can see his music he must be able to see mine... how can I prevent mine from being viewed? If i play one of his tracks... does he know im playing one of his tracks? Some of his tracks are locked and need a password to listen to them but others dont. Just curious.
