If you can't hear the tunes when you click on the tune name it is possible that you are not using the default Windows player.
Try Right-Clicking the tune name to see a drop down box and then Left-Click "Save target as..."
Then navigate to a suitable place on your hard drive to save the file. Remember where you have saved the file and click "Save".
Now open Windows Explorer (Windows key and "E" together), navigate to where you saved the file and double Left-Click it. It is very likely that you have a program on your system that will open the file. Usually, the file will play in Windows Media Player.
