Controversy about copyright infringement laws continues to surround the use of P2P file sharing online. The only way to guarantee you are safe is to NEVER reproduce, distribute or publicly share copyrighted material...and that's not easy to do.
Also, knowing that the RIAA now sues Americans if copy-righted material is downloaded and shared with others via the net, using a file sharing program can be risky. When looking to get music downloads online, it's important to use caution and common sense. And remember, there are a huge variety of legal music downloading options to choose from.
