Usage

YTMusic provides you many ways of fetching data from YouTube Music
To leverage all the functions, we will need to create an instance of the class YTMusic. Then, call the initialize() to initialize the API before using the API anywhere

const ytmusic = new YTMusic()
ytmusic.initialize().then(() => {
	// Use API here
})
