[Bug 7428] Safari 4 preloads media and FF 3.5 doesn't in <audio> tag; perhaps HTML5 sections are unclear or need a 'preloading' attribute added.

The spec says:

The latter sentence is encouraging UAs to do what Firefox does.

No, the browser is in the best position to know what the user's network
conditions are --- whether it's on a phone, or loading content over a very
high-speed network or even the local file system, etc. User preferences are
also relevant here. This does need to be ultimately controlled by the browser.
