After you've selected the song in the media manager, and double click on it, the title under preview window should change to the title & author of that song instead of 'no item loaded'. However, if you right click on the song and select preview, the title won't change, same thing happened if you pushed the button between 'delete the selected song' and 'go live with the selected song'. It is good if you can fix this bug because it will cause confusion easily.
