It's interesting to me that you see yourself as spotify + itunes, as the comparison that immediately struck me is Bandcamp + recommendations and the ability to queue up tracks. It certainly seems like the value you bring to artists is very similar to bandcamp - I suppose your differentiator here is discovery? Are you planning to allow sales of physical items as well? I'm a big fan of buying the vinyl release + immediate download - and anecdotally it seems like the independent music crowd would be more interested in this than perhaps other music demographics.

I'm keen not to make any comments about recommendations or the breadth of music available, as I'm aware that the latter is a chicken-and-egg situation, and the former is hard to judge without giving the site a chance to learn my tastes. I'm going to give it a try for sure.

And now for some classic hn nitpicks:

* Please stop your site links from opening pages in new tabs. Whilst looking about for more information, I ended up with 7 tabs open. Please no.

* I clicked on the feedback tab on the right side and was presented not with a feedback form, but a login form. If I can listen to music without signing up/in, surely I can leave feedback?
