How to make a keypad play audio files?

Hello, im pretty new to ardunio and I want to make this matrix keyboard http://www.miniinthebox.com/4x4-matrix-keypad-keyboard-module-201211270080064_p478899.html play an audio file when a button is pressed.

I have the keypad library and seen the examples but I don't really understand it. How do I set an audio file to be played when a certain button is pushed? I would really appreciate any help thanks.

Im going to bed ill read this in the morning

Hi and welcome. I'm sure you know that keypad can't play audio files and neither can the Arduino. You need something like this I think:
