Umm... First of all, this website is ass old. Second of all, it is infact illeagal to have a link to a website where it shares music that are copyrighted. No matter how good the website is, if it's illegal to share, it is against the rules to have the URL here.
Also, this is one of those illegal websites that you don't go gaga over. I'm surprised the mods haven't done anything after reading this topic... There are better sites to download game music, you haven't looked hard enough.
