From youtube comments:
The music has nothing to do with the videos, Both are awesome and the fact that someone had the idea to put the 2 together is orgasmic. The song is sung by Sonia Devi as it's stated in the description. The videos were produced by Televisa, Mexico's largest Television Producer, to commemorate Mexico's Bicentennial. The videos are meant to show the natural and biodiversity of Mexico which it zealously protects.
