The nice thing about the young generations, at least many of us (we're not a monolith), is that we're a lot more willing and able to go around the traditional route to get knowledge, information, and our things. I've been in a couple audio stores, but mostly walked away unimpressed. The internet has a lot of resources (cough, cough) where I can find out more than most of the people in those stores. And it's less biased than someone trying to make money off of me. That being said, I've patronized those stores, too, but I use them as a service, not a reference source.
And I've gotten access to some pretty amazing things, mostly through the internet. I bought my Pioneer PL-1000 through someone I met on AudioKarma, and my Technics 1610 MKII was found through a friend on Youtube. With one notable exception, I've had great experiences getting equipment through Ebay, too.
There's a whole wide world of wonderful people out there. Unlike the old days, we're not as limited by geography as we used to be.
And while some folks turn down their noses at iPods and MP3s, they've given young folks access to a much wider array of music than was possible for the average person in any generation before. True, the quality isn't the greatest, but if you're listening to music in the car or on the subway, that's not going to matter as much anyway (though I do love the images I've seen of George Harrison's car, which had a 45 changer in the dashboard). I listen to mediocre music on the go and high-quality stuff on the deck back home. In that way, I can enjoy music in a wider array of places and my friends and I can expose each other to new sounds and artists with tremendous ease.
Last week, I was with a friend. I used my phone's loudspeakers to introduce her to Janelle Monae and St. Vincent. The speakers are small, but they're good enough to enjoy a couple of songs (it's an HTC One, by the way, and is has better speakers than almost any portable device I've ever had. Not audiophile quality, but not bad at all - end of plug). This week, she told me she's been listening to the album at home. Likewise, she introduced me to the Tune-Yards, another strange new sound I'd never have discovered on my own.
So we may not do things the way they used to be done, but I think we're managing all right. I'm not trying to start a fight between age groups, but it's annoying to always hear folks saying how us young kids can't possibly understand what music really is without someone telling us. We learn by a mix of listening to others and self-discovery, just like every other generation has. The methods of hearing new stuff has changed, but that's really the only difference. People being born this year, like my infant niece, will discover music that means something to them in the same way my generation has, but the methods will probably have changed even more. I might offer some recommendations or offer to let her listen to my set-up when she's to the age where she'll actually care, but she'll be the one that actually chooses what to listen to and how to listen to it. That's the way it should be.
