Nice work, I really like the idea around various versions of the same song, it is cool to see people's versions and what they do with the original. I really liked the second one with the double bass and the gorgeous singing, although I must say that last version was right up there too and the singing was the best of the four, beautifully sang by Consuelo Velázquez, she really made it her own.
