When you say 'very recent' do you mean it's a current single (ie within last month?) i know the majority of the top 40 singles and probably most of the top 100 (apart from all those Disney ones from Frozen that have suddenly appeared in the charts) and I've ruled out Katy Perry, Rihanna, Beyonce and Shakira as they are famous, plus Clean Bandit, Route 49 (or is it 94) + Jesse Glynn, Little Mix, Hayley Williams, Katy B, Ellie Goulding, Christinie Perri, Lana Del Ray as the videos I know don't match your description
