I don't think I own any pop albums. Very little of the stuff I own is ever heard on the radio. I've never really been a mainstream music kind of guy,
Some people want to call the Beatles "rock" but I don't think it is. It's influenced by early American rock but it is mainly Brit pop with some avant garde drug stuff thrown in. I consider them the greatest pop band of all times, but there is better rocknroll out there.
I was exposed to the Beatles growing up, that's why I'm such a fan, but as I got older my tastes started running away from the middle of the road off to the ditches. I quit listening to corporate radio a long time ago. I listen to some college stations and independant Internet stations, otherwise I discover new music at live venues and a lot bands I like will never make it big. I also like to back and re-discover music from before my time and genres that I've never given much thought to before.
