Egads... whine, whine, whine, whine... I GUARANTEE that musical snobs have been complaining about the decline of the quality of music since polyphonic chording was invented 1000 years ago. Ever since the music industry sorta got its act together with mass distribution in the 1950s or so, there's always been crappy, cheesy music that sells like gang busters. Every single era has its Justin Bieber or Shawn Cassidy. There's plenty of one-hit wonders that sold a crapload and then were abandoned by the music industry going back as far as the 1950s.
My grandparents thought the stuff coming out in the 1960s was utter crap. My parents thought the stuff coming out in the 1980s was crap. My friends all seem to think the stuff coming out today is all crap..... It's an old and trite thought that's been said a billion times before.
There's plenty of great music out there. In fact, the ability for good musicians to get their stuff out to people has never been easier or more accessible. The same tools that allow hacks to put up whatever they want allows great musicians to put up whatever they want, too.
I remember someone doing a psychological study a number of years back. They studied a bunch of people of all ages. They found out that people when they turn about 35 years old stop buying new music, and only buy what they grew up with and listened to in their 20s. It's no coincidence. People get stodgy and pine for the music of yore, no matter how old they are.
Good talent always makes good music, no matter what the technology presents itself with at any given time, and pretty people selling bubblegum music will always outsell quality stuff. It's just human nature. That is the playing field. Now, people can either whine about how better things used to be, or, if they're so knowledgeable, they can step up, go out and create some music that proves just how bad they perceive modern music to be.
