Try early Beatles' songs! They're fun and easy fo listen to and sing along. The easiest one is "Revolution 9" (John Lennon simply repeats "numbre 9" all through it).
Jokes apart, you have "Hello Goodbye", for instance. This is part of the lyrics:
You say yes
I say no
You say stop
And I say go, go, go
You say goodbye
I say hello
Hello, hello
I don't know why you say goodbye
I say hello...
It's longer, but I will leave you the tast to find it.
Hope this helps!
