So I'm working on a project in Garageband on my MacBook Pro, and I have a quick question. When I transfer my song to my iTunes so I can burn it onto a CD, will the click track/metronome sound that is on the Garageband program transfer also? Will I hear it if I listen to my track on iTunes?

And if so, is it possible to turn the sound off?
I'll pretend I can mod your amp but break it instead.

No, Garageband never exports the click sound. But yes, you can turn off the metronome by going to Control>Metronome.
