While I like the sparse design (and badass logo), a huge problem is that I get to site and within the first ten seconds I don't know what it does (or even why I should care). I decide to figure out more by typing an artist and click 'music search' but now it's taking forever. If I was a random visitor, I'd be gone by now.

While I expect the load time after typing will be better as you work on scaling (and work out the bugs), I still think you'd be a lot better off with a little text explaining why I should even type something in and hit 'music search'. Will I get to play music? Will I get to download music? Will I find the cheapest prices for buying music? Who knows. Just my 2 cents.
