Um, I've got no idea how to really do anything in garageband. And I'm wondering things like how to get the synth setting they use like at the start, and the drums etc.

Could anyone help me out on the whole song and what settings i should use etc, or just little bits? anything really!

Or if theres any good guides for anyone new to garageband that you think would be useful to me, if you could point me in the right direction that would be great.
