What are some current dance songs that are appropriate for a high school dance line?

I'm applying for a high school dance line coach and I have to basically "try out" by performing a dance. I want to use a current song (within the past 5 years) but I'm having trouble finding one that is high school appropriate with no swearing, ual connotations, drugs, drinking, etc. that has a really good dance beat. Can you give me some suggestions please?!
