What are some upbeat songs that I can easily change the lyrics to?

I have to write a "cheer" for a group of 7-9 year olds and I'm having a hard time thinking of songs to use.

Previous summers we have used:

Mr. Brightside by The Killers

Year 3000 by The Jonas Brothers

Friday by Rebecca Black

Whats My Age Again? by Blink-182

I was also thinking some of these could work:

Classic by MKTO

She looks so perfect by 5 Seconds to Summer

Move Along by All American Rejects

High School Never Ends by Bowling for Soup

Love in America by JTX

Hey Juliet by LMNT

If anyone has any other songs, or opinions PLEASE HELP ME!!!

Thank you :)
