So...I want to sing a song that promotes peace in an upcoming event for my school...

Can anyone give me some suggestions?

I know the few like:
Imagine - John Lennon
Waiting On The World To Change - John Mayer
We Are The World - USA for Africa
Heal The World - Michael Jackson...
etc. etc. etc.

If not a song promoting peace, just a really damn good song in general or a really inspirational one.

thanks in advance =]

Where is the love?- Black Eyed Peas.

that's the only inspirational song I know that's "sing-able".

Marvin Gaye's "What's Going On" is a classic

Tell Me Why - Will Smith ft. Mary J. Blige

ohh i really like all of the ones you listed...though where is the love is near impossible for me to sing but i still really like that song lol.

any more?
