Why does most new music suck?


Ok I will have some exclusions to my statement. I'm not talking about classical or jazz. My comment is mostly pointed to rock and pop releases. Don't even get me started on rap.... I don't consider it music. I will admit that I'm an old foggy but come on, where are some talented new groups? I grew up with the Beatles, Who, Rolling Stones, Led Zeppelin, Hendrix etc. I sample a lot of new music and the recordings are terrible. The engineers should be fired for producing over compressed shrill garbage. The talent seems to be lost or doesn't exist. I have turned to some folk/country or blues music. It really is a sad state of affairs....Oh my god, I'm turning into my parents.

Oops, my first sentence is incomplete. The last word was to be "interesting".
I was listening to some modern hip hop with some much younger friends (I look about 15 years younger than I am) and put on Talking Heads crosseyed and painless.  The 21 year old girl started grooving to it immediately.   I explained it was made in an era before protools and auotune.   
Even though not my genre, old disco has a much higher level of Musicianship than much of dance music today, which is designed to be disposable.   
There are however bright spots in artists  like Regina spektor, who was Classically trained in Russia, and her pop music shows the complexity of those musical influences.  
Similarly, someone growing up in a diet of Macdonalds would never develop the palette for gourmet (or even whole) food, I believe that's what's fueling the disposable and simplistic music of today.   
I was surprised to find several years ago that my teenage nephew liked Frank Zappa, so there is some hope I suppose.
