Double mouse click on the test to the right of a loudspeaker icon, should open Microsoft's Windows Media Player and play the track.
If your default media player is not Microsoft, it will open your default player. Howerver, most of the music samples on the web site are in .wma format [Windows format], and if your player does not support this format, you will not be able to listen to the music. Some music samples are in .mp3 format.
If you are having problems, try another computer if you can. If still no joy, send us an email and we may be able to email you some samples back.
Enjoy the music!
