A big +1 to Lucas;

If there’s a song on the web with a URL, let it be itself. Don’t download and rename the song, because the minute you do that you break the single most useful thing about it: the URL. Download it, sure, but put the download where it belongs: in your web cache.

Yup. I mentioned this in a list I put together to demonstrate that there’s still a lot of room for innovation left in the browser (though arguably this should be an OS feature .. but then again, where does the browser end and the OS begin?).
