<div class="player" onmouseover="selectPlayer(this)">
<div class="btn absolute">
    <div class="control play rep left">
        <ul>
            <li><span class="btStop">Stop</span></li>
        </ul>
    </div>
    <strong>Música:</strong>
    <div class="slider left">
        <div class="back relative">
            <div class="bar relative"><span class="right" title="Baixar / Aumentar"></span></div>
