This app acts as simple shortcut that creates play.google.com/music in own window (not tab) and binds media keys to player controls. You can change titlebar position by holding Shift and clicking on Close button. You can maximize window by holding Shift and clicking on Minimize button. NOTE: this app is NOT developed by Google. NOTE2: this app is developed for me, to make listening music simpler, so something may not work Source code at: https://github.com/natrim/playmusic-shortcut
