The title says it all. The music of the (insert decade here) is so much better than the crap they're putting out now.
How many times have you heard (or said) this? We have. Numerous times. And it's false.
Listen to your classic rock station. Listen to your "best of the '60s, 70s and 80s" station. Listen to your classic country station. A lot of good songs playing, right?
Of course there is. They only play the good stuff. Give any decade 20 years to sort out what was good and what wasn't and you can make a good radio station out of it.
Good music is in the eye (or ear) of the beholder. Popular music is in the hands of the young and stupid. (we were once in that category).
The good stuff stands the test of time. That is what you keep hearing long after it has fallen out of current popularity. You forget about all the crap that was popular right along with it.
That is why your decade of preference is always better than current music. We haven't had a chance to weed out the bad from the good. That takes 20 years, in our opinion.
In the meantime, if you hear something you like, enjoy it. Share it.
If you hear something you don't like, ignore it, don't listen to it. Don't criticize it.
