how to intercept HTTP traffic from this program?

i used to intercept the http requests this demo program made with Fiddler and then paste them into my program(cos i dont know how to generate myspace tokens)

the program:
http://www.mp3songplays.com/

Now the old one does not work and the new version is out, but the traffic doesnt show up in MS fiddler. Any advice?

anybody?

maybe it send HTTP requests using a different port, not port 80? any way to check?
I need to somehow capture the HTTP requests that program is sending to myspace

You could use a packet sniffer like Wireshark to see the stream? You may then be able to see what the difference is between the old and the new versions in term of streaming parameters and ports/addresses used.
