Nina Simone died in 2003. For those who haven't heard her incredible music, let me recommend 'I want a little sugar in my bowl' and 'mississippi goddamn' to get you started!
You've never heard of Selena Gomez, Demi Lovato, or Ariana Grande? Selena Gomez has had hits like Come & Get It, Hands To Myself, Same Old Love, and more. Demi Lovato has made songs like Give Your Heart A Break, Cool For The Summer, Neon Lights, and more. Ariana Grande has had hits like Problem, Dangerous Woman, and Break Free.
But those three have been around in the music business since the late 2000s - early 2010s. Not everybody listens to today's music, so it is entirely possible for them not to know who those people are.
Literally a teenager right now and have not heard of any of those songs. Got all those singers in the quiz, though, but they're not in my interests as far as music goes.
Nice mix of old and new - also, major props for including Natalie Imbruglia! For those like someone2018 bagging her out - her début single, Torn, while a cover, is one of the most frequently played songs on radio in the world.
Céline Dion, Alanis Morissette and Shania Twain are Canadian. Natalie Imbruglia is Australian. Amy Whinehouse is Brittish. Mostly americans but definitely not almost exclusively.
