Downloading a .wav or .mp3 with Javascript

Question

I need to have a link on my website page download a sound file. I know that if you direct a link to say, a .doc file it will open a blank page and download the file (because the browser can't read the file), but that does not work with sound files- they are opened with a media player in the browser. How can I automatically download this file instead of opening it in-browser?

This is in Chrome, if that makes a difference.

Answer 1

<a href='file.mp3' download='Very-Very-Good.mp3'>download</a>

Answer 2

<a href="javascript:window.open('song.mp3')">DownLoad Song</a>
