Presenting Fox News host Bill O’Reilly and his musings on the evolution of music, inspired by last week’s Grammy Awards:

The good times of the late 1970′s unleashed Madonna, Michael Jackson, and Earth, Wind and Fire. But it all ended when the AIDS scare arrived in 1984. Suddenly, the uninhibited party became dangerous.

Then music kind of meandered around for a while until rap emerged. At first, the anger-fueled recordings were confined to urban radio stations and a niche audience. But when Elton John sang a duet with the white rapper Eminem on a Grammy telecast, rap went mainstream. Massive parental headaches followed. …

Since then, there have been a series of pop superstars but no real purpose or point-of-view in the music which, again, may reflect the current time. I mean what do Lady Gaga and Jennifer Lopez really stand for? Narcissism? Just asking.

The talent is still there. I heard Justin Bieber do a knockout version of Paul McCartney’s classic “Let it Be.” And Bruno Mars with his little hat was pretty good on the Grammy show this year.
