 This was due in part to the inclusion of three tracks co-produced by record producer Timbaland; in interviews before the album's release he had stated that seven of the tracks he worked with Björk on would end up on her album, seemingly indicating that the decision was made to choose other tracks than the Timblaland-produced ones, or else other versions of the tracks.At the time Timbaland had also had recent hits with Justin Timberlake ("SexyBack") and Nelly Furtado ("Promiscuous" and "Maneater"), with him and his protégé Danja being responsible for some of the biggest hits of 2006 and 2007.As the news of Björk's having worked with Timbaland spread across the Internet, many websites started speculating on whether the album would be "hip hop" flavoured; in one interview Timbaland himself referred to the upcoming album as "hip hop".
