"Floods" was written by the band after they watched Al Gore's documentary about global warming, An Inconvenient Truth. Frontman Charlie Simpson said on the band's website, "Like most people I was blissfully unaware of how bad things had become, and I realized that we should all be facing responsibility for the way we behave. It really inspired the whole record, how we treat our planet and our society now, is going to have repercussions in 50 years time."
The video incorporates CGI animated footage from the 2007 disaster movie Flood.
The Boyz II Men hit "It's So Hard To Say Goodbye To Yesterday" is an a capella cover of a song from 1975 by G.C. Cameron that was used in the movie Cooley High to express the feeling of parting ways with high school friends.
