I used to like WinMX until some Anti Piracy group started trying to corrupt all the new songs. They can't really stop you, if you know what to look for and what to avoid, but there's too much work involved now. Basically, if too many people are available for upload, then it's probably a fake file. My rule is, new stuff from iTunes, and more obscure stuff from WinMX. Funny thing is, I only download stuff that I paid for.
