Im making a mix CD for a friend? sixteenth bday?

Im making a mix CD for my friend, she is getting her license she just turned 16. I am going to make her a few Mix Cd's - She likes Country and Rap. Can you give me a list of good songs? I already have 15, but can hold up to 21 on one CD and want to make her a few of them. Any other good songs outside of those genres is fine too
