Garageband is great for recording songs with live instruments.
It is awful at notating music though. Its does have a pretty good midi interface but the notating is pretty limited.
If you are looking to write scores and music Sibelius is much better. I have only used a demo of Sibelius, but still, it lets you do just about anything with the notation. It also allows you to play back what you've written as well.
