Safari using HTML 5 for MP3s

I just noticed that the latest Safari (at least on Snow Leopard) is loading MP3 files natively through HTML5. When you go directly to an MP3 file it shows a player widget that I hadn’t seen before and if you inspect the element it contains the new <video> tag. Pretty neat!

It would have been great if the widget included a download option (even Save is disabled), but option-clicking on the link works well enough.
