I will admit hair bands were huge in the 80s but that kind of scene sort of died out in the 90s and never came back. V is about modern day Cali and that scene is only alive in nostalgia anymore. It would have made as much as sense as having a disco station in IV since it was huge in NYC back in the 70s. In a game set in modern times it makes sense to have a good deal of modern music and rock just is not what it used to be.
Rock is still strong in LA today. It never died. It's just that the buisnessmen who own the radio towers make sure that their untalented family members are front and center...you know...like Nickleback. The same thing on TV. Over half of amerika is rural, but yet, you see none of those accents anywhere on the news medias or TV(and there are just as many educated/graduates in the same fields as yankees), other than a couple reality shows. Music for the last 15 years has been one big ? to most people. It makes no sense, really, But it's obvious what's been going on and who is holding the door open for each other.
Again, this game is set in Cali, but yet there is no Van Halen in V. VH is the biggest baddest most influential band ever to come from there. Ivan Polvich must be...well...I won't even say it.
I am from the northeast and I have lived here all my life so I don't attempt to speak on what LA is really like. I know enough not to speak on things I know nothing about.
I like a lot of electronic music so despite what they left out I did like what they put in. It could have used another hard rock station though.
