-/**
- * @fileoverview provides a reusable mp3 UI component given a mp3 URL.
- *
- * goog.ui.media.Mp3 is actually a {@link goog.ui.ControlRenderer}, a stateless
- * class - that could/should be used as a Singleton with the static method
- * {@code goog.ui.media.Mp3.getInstance} -, that knows how to render Mp3s. It is
- * designed to be used with a {@link goog.ui.Control}, which will actually
- * control the media renderer and provide the {@link goog.ui.Component} base.
- * This design guarantees that all different types of medias will behave alike
- * but will look different.
- *
- * goog.ui.media.Mp3 expects mp3 urls on {@code goog.ui.Control.getModel} as
- * data models, and render a flash object that will play that URL.
- *
- * Example of usage:
- *
- * <pre>
- *   goog.ui.media.Mp3.newControl('http://hostname/file.mp3').render();
- * </pre>
- *
- * Mp3 medias currently support the following states:
- *
- * <ul>
- *   <li> {@link goog.ui.Component.State.DISABLED}: shows 'flash not available'
- *   <li> {@link goog.ui.Component.State.HOVER}: mouse cursor is over the mp3
- *   <li> {@link goog.ui.Component.State.SELECTED}: mp3 is playing
- * </ul>
- *
- * Which can be accessed by
- *
- * <pre>
- *   mp3.setEnabled(true);
- *   mp3.setHighlighted(true);
- *   mp3.setSelected(true);
- * </pre>
- *
- *
- * @supported IE6, FF2+, Safari. Requires flash to actually work.
- *
- * TODO(user): test on other browsers
