You can use any sniffer of your choice. if you use firefox then "Tamper Data" extension can also be used. open "Tamper Data" and in filter use "play.php". Now when you play a song it will show you request url eg:
Code:
http://m.jiwa.fm/play.php?r=51477174&s=12039&t=d07dc699fd28207114cae9c52ba42c75&m=60338&from=0
in above url "s" parameter is song id. in this case it is 12039.
After getting the song id just use the following cmd
Code:
php KSV-Jiwa.php 12039
