How do I create a in-game music library that my character can use?

Hello, I have created both my models character and an iPod. And I was wondering if there is a way that the character/player can use that iPod model to play music during gameplay. In Scarface The World is Yours Video Game, the character receives a submenu box (on the screen) with all of the music in that library and the character/player can select the music he/she wants to listen to and play it during game play. Is there a way to add a sub-menu box to an item and activate it with a single-key/button. Please Help.
