Desensitized song meaning
The smashing sound in the beginning of the song was produced by Mike Dirnt.
This song sarcastically describes how media these days consumes people and takes away their feelings. People watch news about wars, terrorist attacks, suicides and murders as if those were entertainment shows - "bring me blood and pain of a stranger's fate", "go ahead and kill yourselves - it all amuses me". The more news about someone else's tragedy we watch and read - the less we care. We drown in a pile of information on TV and Internet, absorb it all and lose the true feelings of life - become 'desensitized'.
