Music Beta is a browser extension for Google Chrome and Opera browsers, created by developer Benjamin Fry. It allows you to easily play or pause any video playing in your browser on any website in a new tab or window. When the extension is installed, you can add a "Play/Pause" button to your browser's address bar. The extension is based on the Web Audio API, which is available in Chrome and Opera.

The extension allows you to make music controls by tapping the button in the browser's address bar, or a video. It supports audio files as well as videos. You can select the audio to play by tapping the video's play button.

The Play/Pause feature allows you to pause a video or audio file by tapping the button.

A "Skip" feature allows you to skip a video or audio file.

A "Play/Pause" button allows you to start or pause a video or audio file.

A "Restart" feature allows you to restart a video or audio file.

An "Back" feature allows you to open the video or audio file in the previous page.

The extension includes a "PlayPause" icon to indicate that the video is currently playing.

The extension has some minor problems, but the developer is working on it.
