How did a group of 22-year-old Londoners get their hands on a private plane? Which of them is playing that sombre piano interlude? Did Fazer just admit, mid-flow, to ripping off a classic K-Ci and JoJo track? So many questions, N-Dubz, so many questions, none of which I never expect to get the answer to. At least I know this much; in 20 years, a lecturer in some crackpot university will dig up this tune for his Popular Music and Culture course (believe it or not, it's already a thing) as an example of how haphazard Auto-Tuning was crucial to scoring yourself a hit single in 2010.
