The Beastie Boys released an anti-war song a few weeks ago, it
sucks. System of A Down had Michael Moore (I like him) direct an
anti-war video for their song "Boom." That song sucks, too. Lenny
Kravitz recently released a song; now, I haven't heard it, but
since it is from Lenny Kravitz, chances are that song also sucks.
The only good war-song that has been released is "The Final Straw"
by REM. You can listen to it here:

You're welcome.
