I don't think anyone really knows where music is heading. Whereas record companies used to be the ones calling the shots, are slowly becoming "paid" consulting agencies. I've been noticing a large number of ads on Craigslist with "opportunities" to showcase before record companies wherein the winner will receive a "consultation" from said record company. The music of Arcade Fire isn't new. It's nothing but a soft brand of punk that was simply loud and atrocious, lacking all of the statements and means of punk. They sound like most of the Orange County, CA bands that operate down here. Guys who really can't play that well, so they turn it up as loud as they can, hoping you don't notice.
There's no direction and unless musicians find a nice cushy covers gig, if you wish to play originals, you're forced to become and operate like a business with a strong marketing campaign and often a gimmick. It has nothing to do with music anymore. Now, to get a following, bands are videotaping themselves and streaming their shows on the web, and if you can, get money to do a real video and pass it around with as much free music as you can just to entice people.
