I see that you have a PSR S series, I could not see the model number, but, if it is a PSR S970,S770-S975,S775 you could install the Cumbia Expansion and even some more packs, let me know....send me an email....
I know Juana La Cubana.....and your version is very nice, but, I think there are other possibilities if use other styles for the same song.......or just to simply have couple different versions.
