Fortunately, they're doing so with a bang. Recent single 'Don't You Worry Child' topped the charts and showed they had perfected the balance between credible house and Oceana-raving pop, while previous and harder cuts 'Antidote' and 'Greyhound' served their purpose soundtracking this year's club 18-30s.
There's little new to be found amongst the 22 tracks, with around two-thirds being the best of their individual work and remixes served up to other acts; ranging from an atmospheric re-swizzling of Usher's 'Euphoria', a standard dancefloor makeover to Coldplay's 'Every Teardrop Is A Waterfall' and the addition of an ear-snagging hook to Pendulum's The Island.
Of course, it makes for an exhausting hour and 15 minutes - but the intention was never one of a cohesive, journey-leading record. Swedish House Mafia's strength has and always will be in their live act; one whose aim was to pummel you with thrilling and euphoric beats regardless of whether you'd had enough or not. In that sense, Until Now is a job well done.
