What's considered an oldie in music these days?
We're at the point now where any music released with a year starting in 19 is considered an oldie.
Above is a two-and-a-half hour documentary called Heavy: The Story of Metal, which originally aired in 2006 on a cable channel here in America called VH-1. I don't know how long it's going to stay online, so watch it while you can before it gets pulled. (ETA: Yep, it got pulled, sorry, but I still got stuff to say about this.)
Is it any good?
No, it sucks.
Note up front: Yes, I made the above image. It's the "I'm as mad as hell" scene from Network.
