The Google Chromecast device has received a software update to support the ability to stream music and videos directly from Google Play. Now you can visit play.google.com and cast your Google Play music, movies, and shows to your TV directly from the web. You have to have the Google Cast extension installed on the Chrome browser though (download the extension from this link). After downloading and installing the extension, look for the Cast icon in the Google Play web player. Click on the coin and then your move or song will start playing on your TV through the Chromecast.
