Thank you Hyperz. I'll not copy whole program of yours, I'll use only required parts and continue developing my program as my main intention of developing my project was to learn coding.

I'll give you the credit and all others like Jayfella who helped me.

EDIT : You said you posted to help me out. So, I would suggest you to remove the link else you will see lots of this type project within a week. I saw your project is in a much organized way but I am new to coding, I'll improve too.
I'll in between continue in my way of searching from Google because I simply don't want to copy your way. I am interested in learning something myself.

I can't execute your code by F5 , I guess because your version is different from mine. I am using Visual C# 2008, only that not the whole Visual Studio.

By the way, after I get a mp3 URL, how to display all the URL's I extracted so that users can click it to play.

Thanks for your cooperation with my project.
