OpenGl and C++ music - How to play 2 music at the same time?

MH4 (46)
Hi guys I'm wondering if you guys know anything about how to play 2 sounds the same time? Currrently I'm using irrKlang and i dont think that i can play 2 sounds at the same time. Or maybe it could be my code that has a problem? Btw I'm using openGl and im currently trying to do a theme park/carnival. Im now currently doing my drop tower ride.

	glutInit (&argc, argv);

	glutInitWindowSize (800, 600);
	glutInitWindowPosition (100, 100);
	glutCreateWindow ("Pir4tes!");
	glutDisplayFunc (MyDisplay);
	glutReshapeFunc (rescale); // to be called when window size has changed
	glutMouseFunc (onMouseClick);
	glutMotionFunc (onMouseMove);
	glutKeyboardFunc (keyboard);
	glutIdleFunc(doMainLoop);
	bgm(); // my background music


	init ();
	glutMainLoop ();
}

// this is in my music_and_sounds.cpp
#include <iostream>
#include <windows.h>    
#include <string>
#pragma comment(lib, "winmm.lib") 
using namespace std;

void ride_scream (void) {
	PlaySound(TEXT("music_and_sounds/many_girls_screaming"),NULL, SND_ASYNC);
};

void bgm (void) {
	PlaySound(TEXT("music_and_sounds/hikariE"),NULL, SND_ASYNC | SND_LOOP);
};


I had no problem playing just the ride_scream() as when the elevator drops down it does play the music. the only problem is when i added the bgm(). I think that its because of irrKlang but i could be wrong...
