Jelly and chicken nuggets, Marmite and skittles, gravy and cherry pie. Like food items, there are a few words that should never be put together. Of course, occasionally there are mixtures, like chips and milkshake, that seem grotesque in concept, but in reality are an absolute winner. Taylor Swift and Dubstep are one such vocabulary mix that one might repeal from at first sight, yet will warm to on the sound. Swift's new single 'I Knew You Were Trouble' has a hint of dubstep to it, proving the versatility of this normally strictly-country singer-songwriter.

The genre of 'dubstep' has its roots in urban British music of the '90s drum and bass crowds, but it has increasingly found itself being utilized by mainstream artists such as Ellie Goulding and increasingly popularised by DJs such as Skrillex and other artists like James Blake, Benga and SBTRKT. has praised the 22-year-old for branching out into new genres, because it “shows how Swift is growing as a musician”. Swift has commented on the sound of the song, saying ““It sounds just as chaotic as the feeling was when I wrote it.” she said it’s about “being frustrated with yourself”.

This is another of the young singer's teaser tracks from her upcoming new album 'Red', which will be available from October 22nd. Unlike her former albums, this one is being co-written and Swift is collaborating with a range of producers to create a more eclectic sound that will hit a far broader reaching audience. Remixes of 'I Knew You Were Trouble' will hit clubs soon, no doubt, and with that Swift's squeaky clean image is bound to change.
