Okay so I just purchased the new MacBook Pro 13 inch 2.5 ghz and I want to put everything from my last iTunes (on another computer) to my MacBook's itunes. My friend told me that if I open up the iTunes app on my new MacBook and just plug in my iPod and "sinc" it that everything would copy over from my iPod to my iTunes, is this true? Will this work? And yes I understand this will take a couple hours.
