Sampling and remixing is at the very core of dance music culture. Genres like house, garage and jungle owe many of their stylistic traits to the way pioneering producers reworked sampled sounds such as funk drum breaks, disco strings and R&B vocalists.
Relying heavily on sampling comes with numerous pitfalls though. For one thing it can result in copyright issues, creating a need to haggle with the owner of the original source material in order to release your track and potentially end up giving away a chunk of the royalties. It also means relying on the same pool of classic recordings as every other producer out there.
