So Im a Dj and or well used to be and recently got back into it after going through a rough time in my life. I used to have a Macbook pro 17 and I had turned this feature off. Now I have a 15 inch Macbook pro and everytime I download music files off of websites for serato it automatically starts playing in itunes.. every song. and Its sooo annoying I can only put it with it for about 20 minutes before I give up. Anyways how do I turn this off or stop this from happening
