Can you help me find some positive, upbeat contemporary songs?

I am trying to put together some music tracks of contemporary (as much as I like “Don’t Worry, Get Happy”, that’s not what I am looking for) music to give to a young high school girl going through a hard time. I was thinking of songs that are really positive (like Katy Perry’s “Firework”, for example) and upbeat. I was looking especially for songs that inspire.

Any suggestions would be most appreciated.

Thanks, everyone!
