I'm going to completely disagree with the assertion that we're running out of ideas and good music.
I don't know of anyone here who was alive to hear what kind of stuff was new in the 50s, but you can be certain that there were plenty of shit bands and shit records there as well. 99% of everything is shit, and pretending that music, culture, the future, and everything we've ever loved is fucked is incredibly short-sighted - in 2050 (assuming, of course, that the Mayans haven't risen from the dead and summoned down space aliens to kill us with trans fats and Slap Chops before then) people will look back and only see acts like Devin Townsend and Porcupine Tree that just had their shit together the whole way through - they'll laugh at crabcore the way we laugh at poodle skirts, and they'll bitch and moan about their newwavecybergrindgore like we do with whinecore twats. Society isn't declining, we just haven't had the great filter of passing time to pull out all the mindless bullshit in today's music like we've had with yesterday's. We have more exposure to garbage for a number of reasons, but that doesn't mean that we're without stellar acts - or even that they're less common than they were before. Hindsight may seem 20/20, but the fact that today seems fuzzy doesn't mean that the world is out of focus.
