Canadian start-up Viinyl turns single songs into a quick but robust interactive website. Cuurently in beta, think of it as a digital version of the 45rpm single with artwork, lyrics and videos. Viinyl mini-sites come optimized with links to the social web.
Viinyl is also missing a buy button within each mini-site which could just link elsewhere. But all and all, its a worthy concept delivered pleasingly.
