Background music in DirectX C++

[DeadpoolMarvel]

can someone help me please? I'm trying to get my game to have background music as the game is being played I have DirectSound.cpp and .h and in mygame.cpp i have:

//Everything is Initialized, Drawn, Ran  and Cleared fom memory

//include the head file

	//Stop Sounds
	if (sound_BallHit) delete sound_BallHit;
	if (sound_Score) delete sound_Score;

	//function that shuts down the sound
	DirectSound_Shutdown();
	//function that shuts down the input devices
    DirectInput_Shutdown();
	//function that shuts down all drawn sprites etc. 
    Direct3D_Shutdown();
}

Any help would be appreciated.
Thanks in advance :)
