Say you were listening to music on your iPhone in the car, or when out for a run. You get home, and want to start the song up on your Mac. You may think you would have to start the song over, yes? Or spend time ffing to the place you left off? No. All you need to do is get a new app, called Seamless. Seamless works both ways, letting you easily move back and forth between iTunes on your phone or your Mac without missing a beat.
