I built a site for a musician friend of mine who is putting out a new album. Clearly having playable tracks is important, but the classic issue of having those tracks stop when a new page is loaded comes up (like Screencast #81). This time instead of using AJAX, all the content on the entire site exists on one page, and things are shuffled around through jQuery animations. The result is a somewhat Flash-like website, but without all the pitfalls of Flash.
