This is a good track. Post-James Blake, there's quite a lot of music around like this at the moment and it's a little out of my area of specialism and isn't quite right for Drowned in Sound. I'd suggest looking toward the style press in the first instance - if you have a budget a firm called Purple PR might be a good bet for your music (they do Bjork and Jessie J, but are very good around the fashion end of music). There's definitely an audience for this sort of thing but I'm not sure the grassroots internet is necessarily the best first step, and can imagine finding some people to work with a little further up the footchain would make sense. A bit of press coverage in the style press should get certain corners of the industries attention and I'd definitely suggest emailing a bunch of producers to see if there are any guest vocals you could do, as that seems like one of the main ways into the poppier/MOR world, following that Sam Smith template. Really good stuff, best of luck with it.
