Imaginaerum tells the story of an elderly composer, Tom, who suffers from severe dementia. As he has had the disease for years and has regressed into childhood, he remembers practically nothing from his adult life. His music, friends, all his past including the memory of his daughter are a blur in his fragile mind. All he has left is the imagination of a ten year old boy. As he drifts away into coma, it seems impossible to get back what he has lost. Or is it?

In the video for "Bye Bye Beautiful", the four male members of the band are replaced by four female models throughout the verses. Despite speculation, Holopainen said in a Finnish interview that the female doubles in this video have nothing to do with the removal of Tarja Turunen from Nightwish, saying "It's just pure self-irony and rock 'n' roll". The four models are referring to the rumor going around the fans that Anette Olzon, the new singer, was chosen to attract more fans because of her looks. In the video, they make fun of the rumor. The video was released on September 27, 2007.
