  And so, watch as I begin a descent into nerd country and discuss briefly Star Trek and it's complete inability to rock out. I've discussed this with people before, so if you've had the misfortune to hear my rant on this, feel free to tune out. If you're one of the many who've had to listen to my theological beliefs on why I won't eat seafood, you'd know better than to listen to me rant twice on one issue. It'd make your head hurt. That said, Star Trek, and why it will never get groovy with the rock the kids are listening to.
Anytime I tune in to watch some Trek and they discuss music in any form, they're always listening to a classical composition of sorts. Beethoven seems to be a popular choice among the captains of Starfleet. Sitting back, pouring a glass of red wine, and listening to the piano and feeling rather mellow. And this is supposed to be our vision of the future of humanity? Sure, I dig me the classical music. But, variety is the spice of life spaceboys, and just listening to classical doesn't cut it. Why can't Captain Jean Luc Piccard put on some jazz music, or in the very least rock out with The Rolling Stones.
Heck, they're in the future, listening to The Kings of Leon would be considered to be old-fashioned music (though, in many ways, that's the case now). In having seen what could potentially be several hundred hours worth of Star Trek over my life, I can only thing of two instances in which we heard some modern music. The first was in the Eighth Trek film FIRST CONTACT where one of the characters is listening to Steppenwolf's Magic Carpet Ride. While it was nice to hear some actual beats coming from the TV set, it's a shame the films producers couldn't at least have them listening to something a bit more current.
But hey, baby steps. It's the second example that I feel says more about Star Trek in general than any other Star Trek scene in the history of the franchise. There's a scene in the film Star Trek 4 (The Voyage Home) where Captain Kirk and Mister Spock are riding a bus in mid-80's San Francisco. They encounter a punk-rocker on the bus listening to a boom box which is too loud and distresses the other people on the bus. Spock gives the punk a Vulcan nerve pinch, thereby sedating the kid, and turns off the music. And so the one time that Trek actually explores counter culture, it not only mocks it by acting as though it's a menace to the other decent god-fearing folk around, but Spock goes as far as to turn it completely off.
If that doesn't say it all about the series, what does? Star Trek is suffering diminishing ratings and it's current series ENTERPRISE is in serious danger of cancellation. The problem as most people see it, is that the show refuses to evolve and actually explore new aspects of life.
With our world facing such uncertainty these days, Star Trek would be the perfect venue to explore (through metaphor, as is its way) not only the current political climate (terrorism, globalisation, etc), but also to explore the changes in our daily society (homosexuality, the changes in the family unit, toe socks). Instead, it seems content to be stuck in its old ways of listening to Mozart and pouring the fine red.
