lamewire or limewire sucks, too many record companies and studios troll it and try and get peoples IP's so they can sue you for an absurd amount of money.
if you are looking to just get files or albums for that matter, i recommend just finding files on rapidshare or megaupload. there are tons of forums where people post links to music or movies or TV shows. you can just follow the links to the file on rapidshare and download it, that way you don't have that shitty lamewire file-sharing program on your computer where other people can see what you have on your hard drive and try and download what you have and be bringing down your internet speed. plus hackers know how to bypass and get into sensitive files on your HD.
a good site to look for music is at drunkenstepfather dot com and check the forums. just become a member and use the search function, you should be able to find just about anything you are looking for.
and if you are still worried about getting caught, use a proxy, and to take it a step farther , don't use your home internet, use a free internet from places in your town and still go through a proxy.
most people post rapidshare files in a compressed .rar or .zip file, so you'll need a program (you can find for free on the internet) to be able to uncompress them.
