Rate NIN releases from which you think is best to worst. This can include anything (provided you've heard it) apart from singles (so the remix releases, the EPs)

Me? I would say this:

1. The Downward Spiral
2. The Fragile
3. Broken
4= Pretty Hate Machine
4= Year Zero
6. With Teeth
7. Further Down The Spiral
8. Things Fall Apart

(i have not yet heard Ghosts I - IV, but it will undoubtedly be above With Teeth)
