If you aren't familiar with Lorde yet, then you should really search her up and listen to her songs. Probably the current best pop artist of our generation. Yes her genre is pop, as surprising as that may seem. Her songs have souls and meaning unlike the current mainstream pop that we are used to hearing. It's not a wonder she can fill domes of 70k-100k people. 

Her most famous song to date is "Everyone wants to rule the world" which is the soundtrack for Catching Fire, Dracula Untold, Gran Turismo 5, and the newest Assassin's Creed.
