I wasn't using that track as an example of that-track-is-better-than-all-older-tracks - you're missing my point.  I was just noting a level of complexity that wasn't present in much of the earlier tracks.  For an analogy on this specific point, there is a power metal band called Helloween - their later material became more complex, yet most regard their early material as quite better for the level of abstraction they brought. 
I'm talking about the overall quality.  There are a LOT of older tracks that aged really poorly - I don't see any charm in them whatsoever.  I do agree that there are some entertaining tracks of various degrees in the past, but in numbers, I feel that most of the tracks now are quite listenable & enjoyable, but you cannot say that about most of the tracks in the past. 
Also, LOL at Hoboka's post.
