90% of what I listen to is from between the 70s and the early 90s. I'm not big on most of the music from this century, even though there are definitely exceptions. I'm willing to give this century a few more years before I turn my back on its music completely.
I grew up listening to music from both the late 90s and early 2000s. It's all a continuous era to me, so I don't believe one side of the turn of the century is really any better than the other.
