Has music finally lost its charm?

Yesterday while cleaning out my old CD stack I ended up listening to a few and realized that music has changed a lot over the years. The 80s and 90s for me was a time when good music was made. Now in the 21st century we find people like snoop dog and Pitt bull listed in the top charts. What happened to songs being meaning full?
I wouldn't blame the singers completely either as I feel it’s the people as well whose tastes have changed and bands like back street boys have become a fad of the past. There are still a few bands present which do make songs worth listening but that's still a few.
There was a time when vocalists had to have a great voice to sing but now it feels like everyone's a singer. They don't need the talent but money. Where’s the competition, the hard work and passion?
I recall a quote I once read "All good music resembles something. Good music stirs by its mysterious resemblance to the objects and feelings which motivated It." what’s the motivation today? Songs are sung without feeling and there's no emotion to them.
