Songza debugged !

In an earlier post i had posted the link to this site called songza.com which is a music search and play site.

With some quick analysis of the packet captures i found that its nothing more than a "pretty search wrapper over youtube".

Below is an HTTP request/response session that a search generated.

The HTTP Request to songza.com with my search query string "Kandukondain" was

GET /a/query?q=Kandukondain HTTP/1.1
Host: songza.com
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.8) Gecko/20071022 Ubuntu/7.10 (gutsy) Firefox/2.0.0.8

The HTTP response with the contents "GZIP encoded" was:

The GZIP decoded data is as follows

As you can see, all the links are from youtube.
