Part of my music crusade has been to say how impactful events like this are for the music industry. There’s a great comment in the Idolator post on Blender’s closing from the friend of an anonymous flack who doesn’t know which outlets will be left to pitch by year’s end. It’s that bad. That outlook, coupled with the industry’s retreat from promotion in the name of revenue, viz. videos holed up on Youtube with no embedding privileges and the like, music will soon be harder to find than bin Laden!

Heck, even the thing people seem to enjoy most about music online is changing. Last.fm announced this week that they’ll be changing their streaming policies in many parts of the world, setting off a tidal wave of outrage. Powerful music search engine Seeqpod will begin charging developers for its data, too. Ominous noises are coming out of the Imeem camp, too, no matter what they’re telling Michael Arrington at Techcrunch.

Those of us who foresaw the end of Music 2.0 can only shake our heads. Chris Anderson’s “freemium” dream is over. The blue sky mines are collapsing around our ears.

What’s ahead? No one knows. I’m talking to my friend Jason Herskowitz almost daily about the future of music on the web, especially around music discovery. He’s been working on some cool stuff lately, most recently Playdar, an idea I urge you to check out. Nevertheless, he fears that Darknet will soon replace anything remotely legitimate for content sharing online. It’s a frightening proposition for rights holders who have any interest in protecting their properties in this brave new world, and equally scary for those of us who care about music as part of our cultural fabric.
