1. I can't hear sound in Firefox. I am stuck running an older version at work (25) if that makes a difference. Maybe you don't want to support older browsers, so forgive me I'm nitpicking. 2. So I gather the arrow keys help you find related artists. What do I do if I don't like an artist? 3. It says I can jump to an artist by searching in the text field. Where the hell is that? 4. The back button thing, previously mentioned. It's good to keep directions simple, but you've gone to far. From reading the directions, I can't figure out what this does, why it's useful, or even how to use it (where is this text field?)
