WMP 10 Play random song from specified folder

Hi all,
Using VB.Net and WMP 10
Can enyone help me to make the form1 play a random song from a "songs" folder in the same directory?
I managed to list the contents "*.MP3" files in a listBox in the form. but I couldn't figure how to configure this list as a mediaplayer list!!
Is it possible to make it play randomly from that list?

below is the code I'm using.

Thank you in Advance.
