They are not sung by their original artist. I compared them side by side on Djay and they are not the original. It is extremely hard to tell that Fame, Funkytown, Everybody Dance Now, and Jump are not the original but Barbie Girl you can tell by how obvious the voices are between the original and the cover. Although pitch is what gives away the others, it is not as obvious. Mambo No. 5 is obviously the original
