i$e your thoughts on Nine Inch Nails? I see you have Downward Spiral on essentials, but do you like their other stuff too? I'm quite a big fan, although I haven't yet listened to their last (2?) albums after Year Zero.
Just a personal opinion, but 'Rubber Factory' by The Black Keys should be in there somewhere , amazing album (if you like blues rock).
Also, question for i$e or anyone really, I'm getting into Steve Earle's stuff (the country/rock stuff more so than the straight up country stuff), what's his best album? I've only heard a 'best of' album someone made me.
