This might be a little late now, but I uploaded the Hard Corps: Uprising soundtrack a few months back. I'm not sure how it compares to the official release, but I'm curious what people think about it.

Although I'm willing to bet that my upload is probably a lesser quality, especially given that mixi shared the official release. However, that's to be expected when only a gamerip was available back then (like I said in the thread, it's from a torrent).
