Determine a way to identify the button. For example, if your page looks like this:
<header> ... </header>
<section id="songs">
    <button>...</button>
    <button>...</button>
    <button>...</button>
</section>
… then you could get a list of buttons with:
var buttons = document.getElementById("songs").getElementsByTagName("button");
Then loop through the buttons, and call button.click().
