Fetch YouTube Video Info Via oEmbed
oEmbed is a format for allowing an embedded representation of a URL on third party sites. The simple API allows a website to display embedded content (such as photos or videos) when a user posts a link to that resource, without having to parse the resource directly.
Since YouTube supports oEmbed, it's easy to fetch YouTube video/music info via oEmbed api.
