Why is modern pop music today so terrible?

Exactly. Pop music is terrible in all time periods, just probably getting worse and worse. And that's good - let's see how bad bad can be.

Surprisingly, I always liked Bach. Puts me to sleep easily, though. There were others in his time, however, don't remember the names. I heard their music too, Bach was better, to my mind.

Schubert, it appears that you didn't quite get it regarding Elvis. I am not a big fan but do enjoy some songs. White people can sing, sometimes.
