Help getting my apps/music back on my iphone 5?

Well, I just got my iphone 5. And I had an Iphone 4 before hand. I backed everything up before i turned the 5, but once i did. Instead of clicking restore, I clicked backup again. Now I'm having a really troubled time figuring out how to transfer over all of my music and apps. It's all in my Itunes on my computer, I see all of it. But I feel like i've tried everything and nothing works.So, what is a way I can get all of my Music and Apps onto my new phone?

Connect your iPhone 5 to iTunes and it will ask you to restore from a prvious backup (which you made for your iPhone 4) and comfirm this option.
