Hello and welcome to Apple Support Communities, littlepoodlegirl!
I understand you want to transfer the music you've paid for from iTunes over to your new iPhone. I'd be happy to provide information to help you address this.
Make sure you sign in to the same Apple ID that was used to purchase the music on your new iPhone and use these steps:
Redownload apps, music, movies, TV shows, and books
However, if this is your husband's Apple ID, you can use Family Sharing to get this music. Family Sharing is a free feature, you would only have to pay if you made a purchase: Set up Family Sharing
Have a great day!
