It's too bad they called it quits, then. Please enlighten me as to how they're relevant or influential at the moment (I'm being completely serious here). And I just find his music unpleasant.
I am no huge fan of NIN's music either, but look at the facts. The band just celebrated the 20 year anniversary of Pretty Hate Machine, and they were filling arena shows. If that isn't relevant or influential, how about the fact they just used connections with fans to raise money for a patient's heart transplant? The fact they gave away The Slip for free as a thank you to fans? The purchase options for Ghosts was pretty ambitious, and the viral marketing for Year Zero was beyond the scope of any other copycat campaign that followed.
