What do you think about Natalia Lafourcade?
I love her songs! I listened to her Tiny Desk Concert when I was looking for Spanish-singing artists to listen to, and she has a very soothing voice. 
She is known for her ethereal music style. I think she absolutely deserved the Grammy she won for "Hasta La Raiz"
I agree! The first album of hers I listened to was Musas, which has my favorite song pf hers which is "Soledad y el Mar." I think listening to her actually did improve my Spanish. 
Have you ever looked into the translation for "Soledad y el Mar"? It's beautiful. The line when she describes herself as a flower that gives warmth to his life is really cute.
Yes! She has a lot of very poetic songs. I also really enjoyed "Tu Me Acostumbraste" which features a legendary Cuban singer. They sound so good. 
Her voice reminds me of a Disney Princess! Who was featured on "Tu Me Acostumbraste"?
It features Omara Portuondo, who was also part of The Buena Vista Social Club, a Cuban music group that became very popular in the 90s. Also fantastic!
Do you listen to Omara too to help you with your Spanish? I know Omara was known as the Diva of the Beuna Vista Social Club! haha
I listened to Buena Vista Social Club after watching a documentary about them. I've discovered a lot of really good Latin and Spanish artists and I'm glad I can understand some of their songs too.
