Because you're old and set in your ways. Just like your parents were.
I agree with you KP *shiver runs up my spine* but would like to point out that
popular music is at an all-time low these days.
When I was growing up... (get off my lawn you damn kids!) we had Michael Jackson, Prince, U2, George Michael, Billy Joel, Lionel Richie, David Bowie, Phil Collins and acts like that dominating the charts. Now we have Rhianna, Justin Beiber & Nicki Minaj. That's a pretty enormous drop in talent right there.
Sure there's still great music being made but you really have to go out of your way to find it these days with popular culture being as putrescent as it is.
