I'm really trying to guess one, because the drum loop appears at least in two extremely different songs I know, and it's almost impossible that one has been taken from the other, so I suppose that it comes internally in some keyboard. Here they are:
I would venture to say that the Paula Abdul beat is the original and the Fito Paez beat is a sample of Paula's. Listen to how the reverb on the clap cuts off abrubtly on Fito's beat.
The beat on "Sweet Lullaby" is not the same as the first 2 you posted. Not sure where that beat originated from, but I have a CD of looped "hip hop" beats that was made in the early 90s and that beat is on there and I even used it on one of my early tracks (can't seem to locate the tape for that one).
