Music Sampling - Part 2: Motives

Why would authors sample other work?

One answer is that it is an art form, typically found in rap, in which a work uses samples for new and creative purposes.

A more practical answer is that it eliminates the need to produce background and accompaniment music for vocals. This is especially true in rap, since the vocals are often the main focus of the work in this genre. This lowers entry costs and overall production costs, and means that music can be created more quickly.
