DFPlayer Mini Makes my Servo Move at Arduino Startup???

Hello Everyone,
I have the DFPlayer Mini and am trying to use my Arduino Mega to play a few sounds and make a servo move with the use of a button. Everything works just the way I want it to, however whenever I plugin the Arduino the servo moves 60 degrees one direction and back again. The servo was not doing this until I added the DFPlayer code.
Any assistance would be greatly appreciated.
