Song ideas for a school talent show?

Hi, my friend and I are going to do the school talent show next school year. We don't know what to sing, she has between mezzo soprano and contralto voice. I'm mainly a mezzo soprano. We need a clean song with a good beat, we can sing country music, R&B, and pop sometimes. Our group name is Deck of Kards. There's another person in our group, but she goes to a different school so she wouldn't be in it with us. So we need a clean song with a good beat, so we can throw some dance moves in there:)
