I do not recommend using Peer-to-peer networks at all! They contain malware half the time to infect your computer. Ask anyone that is a networking specialist.

You are better off purchasing the music since even anti-virus program won't even protect your computer with P2P.

Update: For the people that use P2P and probably have malware, you are unaware of it. Wikipedia's definition: is software designed to infiltrate a computer system without the owner's informed consent. YOU DON'T KNOW IT'S THERE... removal tools are not 100% and malware can still attach itself after you do a removal. It picks up all types of files that your computer contains... sending them to whomever developed the malware itself. You want to leave an open "pipe" flowing from your computer to another by using P2P, go ahead, but don't complain when your computer is slow or you end up with ID theft because you saved a few bucks on music. This is the reason why malware is invented -> for people like that. Even DoD networks have stopped personal "thumb drives" for the same reason. Malware contains spyware, botnets, keystroke loggers, and dialers that even after running a scan can upload right back to your PC by keeping P2P. You don't even have to be logged in, just leaving your computer on the network and the malware works. Most people leave their computers on network due to using DSL and cable... nothing is wrong with that, but if you have P2P, you are leaving an opened back door to your PC.
