From a thunderous club banger by the Princess of Pop to a return to form from one of the world's biggest stadium rock bands, here's a look at five of the best tracks to have been unveiled over the past seven days.
Britney Spears – "Work B**ch"
The jury's still out on Britney's solo return. On one hand, the faux-British accent, whip-cracking lyrics and obscenely dirty synths provide one of the more distinctive EDM-pop crossovers this year. But on the other, there's absolutely no semblance of a tune. Nevertheless, like previous will.i.am collaboration "Scream & Shout," it will still be utterly inescapable for months to come.
The Killers – "Shot At The Night"
After disappointing with the dreary heartland rock of Battle Born, The Killers have thankfully rediscovered their synth leanings for the lead single from upcoming compilation, Direct Hits. Produced by M83's Anthony Gonzales, "Shot At The Night" possesses a similar neon-lit cinematic quality as the Frenchman's recent work without sacrificing the band's signature sense of pomp and bluster.
Katy B – "5AM"
Continuing to distance herself from her previous Queen of Dubstep tag, Katy B builds on the lush house-pop that defined last year's superb Danger E.P. with this deceptively downbeat tale of a Saturday night out which appears to have ended in tears.
R. Kelly - "Genius"
Never backwards in coming forwards when it comes to matters in the bedroom, R. Kelly self-appoints himself as a sex god on a smooth falsetto-led neo-soul jam which, alongside his unexpected hook-ups with Phoenix, won't do any harm in the quest to reclaim his King of R&B throne.
Katy Perry – "Dark Horse"
The first track to live up to Perry's claims that third album, Prism, will be a much darker affair than Teenage Dream, "Dark Horse" is an intriguing slice of rap-inspired pop which allows the former Mrs. Russell Brand to unleash her femme fatale side, while Juicy J adds to the sense of menace with a guest rap which references cannibalistic killer Jeffrey Dahmer.
