Coldplay have shared a clip from a new song via Facebook. The song has no title but was accompanied by the hashtags #AOAL and #AHFOD. The latter is presumably a reference to the band’s new album, ‘A Head Full Of Dreams’. Coldplay recently appeared to confirm that a mysterious poster spotted on the London Underground, featuring a colourful ‘flower of life’ geometric pattern, is artwork for their new album. Fans of the group took to social media to speculate that the advert, which also had the date December 4 below it, is for Coldplay’s seventh album, citing a similar design on frontman Chris Martin’s T-shirt at the recent Global Citizen Festival in New York.
