    I hope you're not trying to drive the motors directly from the output pins ...

Reset to default

As you did not give details I assume the following:

  • You supply the MEGA via USB or external 5-12V power supply
  • the motors are supplied via an extra external 12V power supply with sufficiant amperage
  • All cabeling is checked and correct

Looks like this schematic (without 12V power supply attached to the motor shield) AF_motor_shield_v1 AF_Motor_shield_v2

To your code:

  • Get rid of the delay()s - they block processing so what happens:

     motor.run(FORWARD);  // => You give a command via lib
 delay(2000); // You stop your processing so the motor is not running

so you have two options both need the definition of a timeStamp var

  • working with a (blocking) while loops
  • or creating a finite state machine (search here on SO for details)

So I will for simplicity use the first approach

 // Copy this var before your setup
 unsigned long timeStamp = 0;
// use your complete setup 
 void setup(){...}
 // Change your loop functions like thes first three converted lines 
 void loop(){
  timeStamp = millis();
  Serial.print("tick");
  while(millis()-timeStamp < 2000){     
     motor.run(FORWARD);
  }   
  timeStamp = millis();   // resets the time to current
  Serial.print("tock");
  while(millis()-timeStamp < 5000){     
     motor.run(RELEASE);
  }
  timeStamp = millis();   // resets the time to current
  Serial.print("tack"); //first song starts 
  while(millis()-timeStamp < 2000){   
     motor.run(BACKWARD);
  }
// .... AND SO ON .....
}

Be aware that the whiles are blocking but for your sequential processing its ok.
