According to Win Butler, the singer-songwriter and leader of Arcade Fire, his band's new hour-long album, The Suburbs , could have been longer. "It was a much larger set of songs," he said during a two-hour interview in Quebec City, Canada, for the feature story in the latest issue of Rolling Stone . "We kept refining and editing back." He estimated the number of songs he and his wife, singer and co-writer Régine Chassagne, brought to the band, in some form, at "30 or something. There were a couple that were not related" – a reference to the record's themes of teenage angst, abandonment and escape. "There's a chunk of them that just sound like they were from a different planet."
