Discord.js Music Plugin

This version is not yet stable, although has been mildly tested, it has not been that extensive.
It's an update of the original by ruiqimao for Discord.js's version v11.x, and adds a few extra sprinkles. It still requires tweaks and testing but yeah it's something.

The commands available are:

• play (<url>|<search string>): Play a video/music. It can take a URL from various services (YouTube, Vimeo, YouKu, etc). You can also search using a string.
• skip [number]: Skip some number of songs. Will skip 1 song if a number is not specified.
• queue: Display the current queue.
• pause: Pause music playback. (requires music manager)
• resume: Resume music playback. (requires music manager)
• volume: Adjust the playback volume between 1 and 200 (requires music manager)
• leave: Clears the song queue and leaves the channel.
• clearqueue: Clears the song queue.

Permissions:

• If anyoneCanSkip is false then only admins and the user that requested the song can skip it.
• Only admins can change volume or resume/pause music.

Things added:

• Search is working again.
• Added the command 'volume'
• Added the command 'leave'
• Added the command 'clearqueue'

Things changed:

• Permissions

This is a music plugin for Discord.js. Using it is as easy as:

const Discord = require('discord.js');
const music = require('discord.js-music-v11');
const Bot = new Discord.Client();
const token = "<auth_token>" // Recommended to load from json file.

Bot.on('ready', () => {
    console.log(`[Start] ${new Date()}`);
});

music(Bot, {
	prefix: '-',     // Prefix of '-'.
	global: false,   // Server-specific queues.
	maxQueueSize: 10, // Maximum queue size of 10.
	clearInvoker: true // If permissions applicable, allow the bot to delete the messages that invoke it (start with prefix)
});
Bot.login(token);

The module consists of a single function, which takes two arguments:

/*
 * @param {Client} client - The discord.js client.
 * @param {object} options - (Optional) Options to configure the music bot. Acceptable options are:
 * 		prefix: The prefix to use for the commands (default '!').
 * 		global: Whether to use a global queue instead of a server-specific queue (default false).
 * 		maxQueueSize: The maximum queue size (default 20).
 * 		anyoneCanSkip: Allow anybody to skip the song.
 * 		clearInvoker: Clear the command message.
 * 		volume: The default volume of the player.
 */
music(client, options);
