some would argue that predictable and/or compulsive contrarians are the problem :)
but seriously, there's a nice middle ground between obsessive nostalgia and a lack of appreciation for one's roots, which entails respecting and celebrating the past while simultaneously looking towards the future
Why respect the past if it is irrelevant to you?
Yeah sure, celebrate it though.
I just see over reminiscience in music scenes as a sign of people growing old and losing touch.
