Music shield with remote control

Hello,
I am using Arduino Uno with Music Shield V2 and i want to control it with my infrared remote control.
I have some problems calling the functions in Music Player with my program, can anybody give me a hint please ?!?!

#include <SD.h>
#include <SPI.h>
#include <arduino.h>
#include <MusicPlayer.h>
#include <IRremote.h>

const int sensorPin = A0;
long voltage, cm;
int sum=0;
int average=10;

//int delayTime = 450;//pauza intre aprinderea ledurilor

int LED1 = 3;
int LED2 = 4;
int LED3 = 5;
int LED4 = 6;
int LED5 = 7;
int LED6 = 8;
int LED7 = 9;
int LED8 = 10;
int LED9 = 2;

int IRpin = 11;
IRrecv irrecv(IRpin);
decode_results results;

void setup() {
// put your setup code here, to run once:
Serial.begin(9600);
irrecv.enableIRIn();
player.begin(); //will initialize the hardware and set default mode to be normal.
player.setPlayMode(PM_SHUFFLE_PLAY); //set mode to play shuffle
player.scanAndPlayAll();
}

void loop() {
// put your main code here, to run repeatedly:
if (irrecv.decode(&results))
{

  irrecv.resume();   // Receive the next value
}

if (results.value == 16582903)
{
player.play();
}
}
void playNextSong() {

if (results.value == 16625743)
{player.opNextSong();}
}

void playPreviousSong() {
if (results.value == 2797147069)
{player.opPreviousSong();}
}

void sonar() {

for(int i = 0; i < average ; i++)
{
voltage = analogRead(sensorPin)/2;
sum += voltage;
delay(5);
}
cm = (sum/average) * 2.54;
Serial.print("Distanta: ");
Serial.print(cm);
Serial.println(“cm”);
sum = 0;
if (cm < 100 )
{player.play();}
}
void volumeUp()//User-defined function
{
if (results.value == 46690913)
{player.opVolumeUp();}
}
void volumeDown()
{ if (results.value == 3001999165)
{ player.opVolumeDown() ;}}

void StopMusic() {
if (results.value == 3495072293)
{player.opStop();}
}
void playPause()//User-defined function
{if (results.value == 211564353)

{static boolean flag_on = 1;
if(flag_on) player.opPlay();
else player.opPause();
flag_on = !flag_on;
}}
“”

I can only call the “player.play” function, afterwards , there’s nothing i can do anymore.
Is there a problem calling the ctrlState ??

boolean deleteSong(char *songName);

void keyDisable(void) { Key_Disable = 1;}
void analogControlEnable(void) { Analog_Enable = 1;}
void digitalControlEnable(void) { Digital_Enable = 1;}

void play(void);
void midiDemoPlayer(void); //oliver wang
