People listen to The Beatles, but while they were muscially influential, they weren't culturally influential in quite the same way. You can go into the back of beyond in a little Indian village, and they will listen to Bob Marley. But they're not going to be listening to The Beatles or The Rolling Stones.
I was a teenager in the '80s, and I was always a bit dismissive of Houston, as I think a lot of people who considered themselves 'cool music fans' were. She was poppy, bubble gum, making music not considered very cool. But you can't help but dance to some of those songs or feel emotionally affected by 'I Will Always Love You.'
