I'm new to the Trent Reznor fan club, having heard 'Spiral' years ago, which left me cold. The lyrics didn't gel and i couldn't relate to someone that depressed.
Having started my NIN purchases with Year Zero, the level of expectation hovers above reasonable, but 'Ghosts' does not disappoint. If you're a fan you own it, and you can download it for $5 on the NIN website.
One thing i have to comment on though is the NIN fanclub - hilarious! Even Amazon states in reviews for both 'Ghosts' and the fantastic follow-up 'The Slip' that they're the greatest releases by NIN - seems no-one can make up their minds.
Just enjoy - who cares which release is best?
If they're good they're good - and they are.
