It's really quite depressing when people say "there is no good music anymore." I tend to think the listener has become complacent and will not branch out and have an open minds to what else is going on. Even though there are many more genres, the same harmonious beats and rhythms that one likes can be found again and again in different music. I grew up on oldies and motown (from my father), and neil diamond, billy joel, elton john, the Beatles, Pink Floyd and all the other 70's and 80's culprits from my two sisters. Growing up near Detroit, I got into hip-hop and finally jazz, classical, and electronica.
I have well over 20,000 lossless songs on my digital hi-fi system. Seems like a lot of music, but I always crave more. And there is a magnitude of new music to be discovered.
It is like food. Some will like beef while others hate the taste. Some like candy while others savor the salty. I am sure most of us can say that 90% of tv channels are worthless. Same old crap. But the others can be fantastic, educational, and well made. Thats how I have always seen music. trying to find that 10% of greatness can be difficult but it's out there. Most of that 10% won't be played on the radio so it is up to the individual to branch out, listen to most of the music, and weed out the good stuff. Every tuesday is when most major albums drop. I usually spend an hour or so on i-tunes listening to all the new albums on that day. Sometimes I will find 1, sometimes I will find none. Its a good place to start to get exposed to different music.
