Here's a fun way to feel old: go to a record store!

I hadn't been to one in ages, but some friends were visiting and we went to one that we used to go to in younger days. They had been to another store earlier in the week, and in that store, the music is organized into "Then" and "Now" sections, and it seems that everything they were interested in was in the "Then" category. And at this one, the definition above. By that definition, every band that already existed by the time i became interested in music is now Classic Rock.

I had always thought the definition was less fluid and more about a specific genre and era (maybe everything from the Beatles to Led Zeppelin), but record stores are obviously in the business of selling records, not creating taxonologically accurate categories, and they would like you old people to go over there, please. Over the in the corner, so you don't scare away the few young people that are actually considering coming into a store to buy physical objects that contain music instead of just downloading it.
