I posted this on Facebook but when I was reading the Wikipedia for the album I noted this about the last track:
I only own this one Offspring album, but it turns out Change the World is the final track on the next album, Ixnay on the Hombre. Anyhow, this is right: that track begins with this quiet little drum and guitar instrumental. But to me it's always just been a reworking of the Genocide riff.
(This also lead me to discovering people mishear Genocide's Dog Eat Dog lyric as 'Donkey Kong' )
