Nineteen-year-old Scot Nina Nesbitt has skipped insouciantly down the contemporary route to fame. Posting cover versions on YouTube at 16, she received early endorsements from Ed Sheeran and Example, and won the iTunes new singer-songwriter of the year in 2012. Peroxide is the most pre-ordered debut album in Island history; those fans are known as Nesbians. There are depths here: Selfies, the single, is not merely some slice of catchy meme-pop, but reflects on the madness of taking fake-happy selfies after a break-up. Largely, though, Nesbitt's teenage insights are buried in functional, anodyne pop music, a tactic that won't be a barrier to success.
