Use the mediakeys to control Google Music. This simple extension supports the "play/pause", "previous track" & "next track" mediakeys of your keyboard as well as 2 configurable keys for the "thumb up" and "thumb down" buttons. No more clicking around your browser tabs to quickly control your Google Music! The keyboard keys configuration can be accessed through the menu (More Tools -> Extensions -> Keyboard Shortcuts (bottom of the screen). Press the "play/pause" on the Google Music UI to activate the extension. This tells the extension which tab to focus on when multiple Google Music tabs are currently loaded. Version 0.0.2: better play/pause status discovery when multiple google music tabs are present.
