it was james Blake, now its easy to target Jamie XX - easy to hate
There's actually two different issues with Blake and Jamie.
With Blake, after a good period of making dubstep that depending on your tastes, was excellent, the guy started making something that was less 'beat-driven' and more 'song-oriented'. He's not a real song-writer, but he gets adulation why...? Because of his prior successes musically.
With Jamie, there is a vampiric relationship with dance music. While I'm sure Jamie does listen to and enjoy dubstep (because I'm sure he doesn't walk around saying he likes 'post-dubstep') he contributes nothing up to this point. But he's guaranteed a degree of adulation because of his status OUTSIDE of dubstep. Which again, is no different than Skrillex or the kids from Enter Shikari making dubstep and having their own pockets of fans that keep them successful, without ever having to be organic. Just a different tempo.
This would be entirely different if, you know, he'd actually been putting records out beyond that goofy "Space Bass" mix. If this was just him releasing these low-key, it'd probably be fine. But BECAUSE he got on Numbers, BECAUSE he's Jamie XX and he's guaranteed focus, that's the big underlying problem.
