Yes, we all know you can view and listen to other people's libraries.
If you want to download their shit, get myTunes redux. Just google it and download it. What it essentially does, since you are on the same network, is upload their files onto your computer while still remaining in the network. What is nice about this is, you get hundreds of thousands of songs at your disposal, and also your SCHOOL CANNOT DETECT THE FILE TRANSFER, unlike limewire and all those other shitty things =)
the only way they could tell is if you like, flood your port, which means downloading pretty much 1,000 songs a day.
Happy downloading.
We'll have you dead pretty soon.
