5) Known New Songs

Soundtrack songs and unreleased tracks might be a hint at what album four sounds like. As previously mentioned, The Hunger Games featured two dark, brooding songs for the soundtrack while their Haitian trek saw the band play another unreleased tune "Crucified Again."

Meanwhile more ArcadeFireTube Twitter posts said one song at the secret club gig had a punk quality to it. As far as lyrical content, ArcadeFireTube said some described it as "rooted in the mid 19th century and the African American history in the US."
