// So, here is why this is a little weird.
// The Shoutcast server software has the ability to provide web pages. These pages just happen to be served from the SAME address as the media stream.
// Putting a "/;" at the end of the Uri will tell the Shoutcast server that we aren't a web browser, so stream the data. The problem is that not ALL
// Shoutcast servers are configured that way. So, we have to do a request to get the content type. If it is text/html, we append the "/;" and move on.
// If it is an empty string, 99.9% of the time, this will be the media stream (If it's an ICY stream, the ICY "headers" don't parse properly). The ShoutcastStream
// will handle this case, so we let it go through.
