Would like to use what I made – GarageBand Review

It's nice. I've had it for a while now. I've just started a YouTube channel and people are wanting me to make intros and out tros to my videos. And I don't want to use what they give me to make them. I want to use something I've made. And with this app I can't save the song I've made to be able to use it. It's really frustrating. Also. Your app support needs some serious updates. If any one can help please do. I'm only upset because I made a sick beat and I can't use it! ?
