Even as a kid, if I would come across something cool in the record store, that would be how I found out about bands. It's kind of the same way these days. In a way even less because there are no record stores to go to anymore.
I can understand why those bands do it. It can be a hell of a lot of bloody fun. People are allowed to have a bit of fun after the age of 40, and a lot of them do need the money.
