If you are unable to play music on the web site www.turkishmusic.org it is most likely that you do not have Real Player installed. When clicking on a link to play music on the site you will receive a pop up asking if you want to open or save a file named t1.pl. The pop up will look like the below.
To resolve the issue just download and install Real Player here. After installation of Real Player you will be able to stream the music from TurkishMusic.org.
A short explanation of the problem is that the design of the site uses Perl to call .ra files which are Real Audio files. So if Real Player is not installed the .ra file never starts to stream and the Perl script does not have any error checking capabilities to warn you of this so instead it attempts to execute the Perl code.
