If you have ITunes, you can probably type in the names of the songs and listen to some samples online. Here is one
http://www.joseluisorozco.com/vol12.phpAmazon has some too if you don't have ITunes, I don't have any Orozco CD's personally but have heard good things. From the samples I have heard it is very traditional sounding music.Search under MP3's on Amazon and you can listen to clips, he has has a website.

I think there are lots of artists that sing these traditional latin american folk songs, you can search amazon/itunes & find a style of singer you like.
Whistlefritz has a CD out called "A Bailar," it has diez deditos and de colores on it, along with Los Pollitos which is a favorite in our house.
