Songs that go with MLK's non-violent philosophy?

[Jazz]

I'm doing a Civil Rights Cd Cover project.
and the goal is to find 5 songs from late 1950's to the 1970's, and 5 songs from the 80s to now that could possibly be something that the followers of Dr. Martin Luther King Jr.'s non-violent philosphy would have listened to

i already have, "why can't we be friends" and "stop the violence" and "we are the world"

but i still need more. help please
