What music should I add to this playlist?

I do gymnastics at a local gym on the “off-competing” season and usually, I’m the oldest in the class. It really helps if you are working out to music and the only thing my coach has it Disney junk like Radio Disney, Hannah Montana etc. She says it would be ok if I were to make a playlist of songs to be played during class. What suggestions do you have? They have to be somewhat appropriate, like ages 10–15.
