Interpolation (popular music)

In popular music, interpolation (also called a replayed sample) refers to using a melody‍—  or portions of a melody (often with modified lyrics)‍—  from a previously recorded song but re-recording the melody instead of directly sampling it.^[1][2] Interpolation is often used when the artist or label who owns the recording of the music declines to license the sample, or if licensing the piece of music is considered too costly.
