B.Y.O.B. (song)

"B.Y.O.B." ("Bring Your Own Bombs") is a song by American heavy metal band System of a Down. It was released in March 2005 as the lead single from their fourth album Mezmerize. Like their earlier song "Boom!", it was written in protest against the Iraq War. The song reached number 27 on the US Billboard Hot 100, the band's highest peak to date on the chart. Casey Chaos claimed to have helped write the song in 2002, and Malakian offered to gift him a 2% royalties credit. When Chaos asked for more, the offer was rescinded. Casey Chaos then subsequently sold a 50% interest in the song to Maxwood Music Ltd. However, in 2010 a Manhattan court ruled Malakian and Tankian to be the sole writers of the song.
