'Can the <link> tag be used to prefetch audio files?

I can across rel="prefetch" attribute of <link> tag. On MDN, they just showed prefetching CSS files.

More specifically:

Link prefetching is a browser mechanism, which utilizes browser idle time to download or prefetch documents

Besides prefetching documents, can it be used to prefetch audio files too?

html prefetch

Solution 1:^[1]

It guess it works for anything, audio, video, images and so on:

<link rel="prefetch" href="foo.mp3">

and inside your body just put

<a href="foo.mp3">foo.mp3</a>

It's cached now...
