Bow down before the one you serve

I'm definitely going to have to buy a NIN album when I have the funds. Working with my character Malorie...most of my music collection doesn't appeal to her for some reason. But she seems to like NIN. However, my small stash on NIN songs just doesn't cut it. So yes, apparently first bit of money is going towards an album. I'm thinking...Pretty Hate Machine, The Downward Spiral, or The Fragile. Whatever's cheapest ~_^
