Good songs for a child audience? Especially ones that have to do with keeping promises, telling the truth or dealing with a bully?

Working on music and sound for another play (about a talking dog who helps a schoolgirl who is teased because she lost her father)... one for audiences age 5 and up this time. What are some good songs I can use? Here’s what I have so far:

Jingle Bells (the dog barking song)
Who Let the Dogs Out
School Bus Driver (The Stop Song)- Daddy a Go-Go
Fathers and Daugthers- Paul Simon
Me and Julio Down by the Schoolyard- Paul Simon
Milk and Cereal- G Love and Special Sauce
I Wanna Be a Dog- Barry Louis Polisar
Hey Little Doggy- Dave and Tawnda/Koolsongs
Sandwiches (are Beautiful)- Bob King?
Best Friend- Lisa Loeb
The Climb- Miley Cyrus
Let’s Get Crazy- Hannah Montana
Friday Night- The Darkness
Burnin’ Up- The Jonas Brothers
Wonder Pets theme (the phone is ringing)

I was thinking about adding a kids version of “Boom Boom Pow” since it seems like every kid on the planet likes that one.
