It feels like ages since we first fell in love with US-born, Swedish-bred crooner Mapei's 'Don't Wait', but now our patience has been rewarded with her new single 'Change'. Hey Hey, her debut LP, is out in September; and like this sparkling, marching-drum-led club banger, the majority of it was produced by Magnus Lidehall - the man behind hits from Katy Perry, Sky Ferreira and Britney Spears. Listen out for probably the biggest, ballsiest Scandi-pop chorus of the summer thus far.
