小迪

#include <LiquidCrystal.h>
LiquidCrystal lcd(8, 9, 4, 5, 6, 7);
int readkey;
int music=0;
void setup() {
  lcd.begin(16, 2);
  lcd.print("Welcome to Play");
}
void loop() {
  lcd.setCursor(0, 1);
  if(music<0) music=20;
  lcd.print("Select ");
  lcd.println(music);
  lcd.print(" song");
  readkey=analogRead(0);
  if (readkey<50) {             //
  lcd.clear();
  lcd.print("Music player");

  delay(500);
  }
  else if(readkey<195) {        //UP
    lcd.clear();
    music=music+1;
    if(music>20) music=0;
    lcd.print("Choosing music");
    delay(500);
  }
  else if(readkey<380) {        //Down
    lcd.clear();
    music=music-1;
   lcd.print("Choosing music");
    delay(500);
  }
  else if(readkey<790) {       //
    lcd.clear();
    lcd.print("The music stops");
    delay(500);
  }
}

顯示出來的music值後面會有怪怪字 求解如何用掉
