Cesária Évora has one of the most beautiful voices I have ever heard and she sings in Portuguese, which is one of my favorite languages (which just adds to her awesomeness, hehe). Seriously though, I love both the lyrics and melodies of her songs; they rock! She just released a new CD, but I have not heard it yet, unfortunately. Without a doubt, one of my favorite songs EVER is "Tiempo y Silencio." She has other very good songs such as "Sodade" and "Petit Pays" but you should definitely check out all her work.
