Garageband free?

Hi everyone

Maybe that someone else already ask this question, but i couldn't find any good answer so far.

I want to know if the Music that you create with Garageband is 100% Royalty free.

Because i am actually programming my mini game and i want to be sure to have any problem with Apple.

I hope to get my mini game published on Appstore after that.

But i really want to be sure that i will not have any strike from Apple Team.

Thank you

Fani
