OPTIONAL STEPS
Use the attribute class="slignore" to hide regular links to music files from the Sideload for Internet Explorer and Sideload for Firefox plugins.
<a href="url_to_file" class="slignore">...</a>
If regular links already have a class attribute, add slignore to the attribute separated by a space.
<a href="url_to_file" class="existing_class slignore">...</a>
