A counterpart of Covered Up when song number 1 gets sampled in song number 2, and song number 2 becomes so famous it eclipses song number 1. Maybe not to the point that people forget about the sampling, but to the extent that most listeners would probably draw the connection between the two when hearing the original. This shouldn't be confused with interpolation - sampling involves taking a chunk directly out of one song, whereas interpolation means replaying it on your own instruments.
