Taught about films and music and you really see the age gap in place. Had a class where most had never heard of Indiana Jones. Hip hop was the most popular music. I nodded along, but couldn't get into it. Maybe it's always been like that. When I was at school there was only me buying Bowie's Outside album and only a few really into the excellent alternative stuff of the time. Most were listening to pretty poor music. Not sure why people listen to bad music really.
