Oldies are now music that was new when I was a young kid?

I don't feel old, and I grew up with the classic rock because my sister used to play 45's in my hearing (she is seven years my senior) and used to bring me along to her girlfriend's who lived in the next block and had a record player. Her parents didn't mind, but ours downgraded our tastes as "bebop" and hated our choices. They liked Mitch Miller.
