I'm pretty sure there are but what kind of music are you talking about. It is possible to download free legal music with p2p and over the internet but if you are thinking of downloading illegal music then places like this are not the place to ask as it is illegal.

Just thought I'd let you know as some people still post things for illegal downloads on legit sites and don't realize it.

Please note: 

As previously stated.  P2P networking is extremely dangerous to the security and stability of your PC.  In effect, you share a folder over the internet.  With very little fiddling, a hacker can easily obtain access to your entire hard drive, including bankcard passwords, SSN, and other personal information.  What you save in having a nice music library may end up costing you a fortune in identity theft.  You can download Legit music at very reasonable prices from sites such as Microsoft Media, Sony, etc.
