Looks like you are in luck because i promote south american music from most parts of south america. What type would you like modern traditional ? (1600's and up) or pre-columbian (be fore colonization)traditional? i have music of african, european, and native sotuh american descent and its fusions.I have mp's and i can also reformat flash files like youtube vids into mp3's. (see my list at the bottom)
Some examples are the traditional music brought from african slaves to colombia called cumbia (not to be confused with the mexican knock off version). Note there are different variations from hardcore traditional to a modern influence with percussions.Some brief examples of the traditional.
traditional dance
Music video
Modern version of cumbia with accordeons and percussion
The modern variation for the clubs :discotecas .It's a venezuelan band but we share the same hisotry so i give it a go.They have a remarkable job of perfoming the colombian cumbia very well if not better at times.P.s. the chic is hot.
If you want purer African music in Colombia there's mapale and currulao
currulao without dancing
mapale
and that' just the african part of just colombia alone other south american coutnries have their own african music depending on which tribe came from africa.
Take the saya from Bolivia that combined with indigenous music
Speaking of which i have native music from ecuador,peru, and bolivia.
san juanito from ecuador in both native and spansih

Lastly here is a traditional song of european descent from my country colombia called san juaneero (litteraly st. johnner in honer of st. john unlike san juanito "little st. john"from ecuador which isn't to honer st. john).the title says queen of bambuco but san juanero is an off shoot of bambuco
