Manu Chao hands down. He sings in spanish, portugese, french, english, arabic, and a language found in Senegal by the names of "wolof".
He blends a wide variety of world beats to his music, which definitely cannot be defined in one category.
Just recently got into him. His live albums are by far superior to his studio albums, but both are phenomenal.
You should also check out the band he formed with his brother and cousin before he went solo... Mano Negra.
Hope this helps!!
