According to me site is good, concept and domain names are really good, you should use nice logo for your site than the current one
I agree with Ryan. Content is key and site is pretty empty. Add some content and I think you'll be fine.
Simple, and of course fast loading. But in my opinion, if your theme is about the music, much better if you also show pictures of the artist, and I think it is one thing that can attract visitors. Thank you.
