Cool concept, would be interested to see it in action. It's probably something I'd use a few times but would only use regularly if it showed interesting videos within the first few tries. Music is easier because it can be tuned out in the background, while videos demand almost 100% of the viewers attention. So if you're asking for that much attention, you better deliver =].

That said, please refrain from the animations in the website's content. Although it's trendy to have scroll-initiated animations, it really bugs the shit out of me and makes me feel like I'm being treated like a toddler.
