THE OLD AND THE NEW (just a consideration)

I'm wondering why if I think to new album or CD  in 2011 I have on the top of my list names like:
-Wire (Red Barkled trees)
-Peter Murphy (ninth)
-Red Hot Chili Peppers (I' m with you)

and only after names like:
- Kaiser Chiefs (The world is medieval)
-Arctic Monkeys (Such it and see)
-Radiohead (The king of limbs)

The answer would be that I'm old and I like old sounds or ....another possibiliy is that really there is a quality gap between the "old" bands and the "new" ones........
Anyone is  free to add his own opinion on this!!
