I think classic rock is any album that came out in the 60s or 70s.

I wonder why '50s rock isn't considered classic rock.

Because "rock" and "Rock n' Roll" aren't the same thing.

And what is the difference? Please explain technically, as I won't take an explanation along the lines of "Chuck Berry is rock n' roll, Rolling Stones are rock".

Well, it may be semantics to you. Look into it for yourself if you're really interested. There's all kinds of rock music, but it's not all rock n' roll.

Here's some wiki links-
Rock n' Roll
Rock Music

I'd say it's mostly down to the beat. Rock n Roll is dance music, where as you can't dance to all rock music.

"Rock n' Roll" by Led Zeppelin is a good example of a rock band playing a rock n' roll song.
