<div class="spoiler"><div class="spoiler-toggle">Spoiler!</div><div class="spoiler-text">Cry my name, remind my brain of my identity
<div>I'm not gonna listen, I'm not my volition</div>
<div>I'm sha na na na na na free will</div>
<div>Am I to blame for riding this train right by my destiny?</div>
<div>Ah, prove I can crack, ah, loose from the track, ah</div>
<div>Sha na na na na na free will</div></div>
