Can't imagine you listening to chart pop music though Marco, which is what this thread at least started off being despairing about.
Yes there are plenty of decent bands and good new music around, the issue is that business imperatives have resulted in commercial pop - the lowest common denominator stuff that you can't avoid as you go around and about, whether it's at the barbers, the pictures, or the Co-op - has shrunk in scope, variety and ambition, in ways that are not a matter of opinion but are absolutely demonstrable (per the original clip). Regardless of what other good stuff is around, it's a matter for some sadness and regret that this has come to pass.
Being a classical guy, I don't tend to seek out bands and so on (I'm busy enough keeping up with my own favoured genres) so my main experience of 'today's' music is the mass-market pap that's everywhere and I have to say, it's no surprise to me that it's measurably less varied melodically, harmonically, rythmically or structurally, than what was around even 20 years ago never mind 40 or 50, while at the same time more and more being compressed to buggery in the loudness wars, as we can all hear.
It's kind of irrelevant that there is lots of other good stuff around if it is primarily this that the great unwashed are being exposed to. Our communal experience is being degraded and no amount of praise for non-mass market stuff can really get around that.
