In popular music
Remixes have become the norm in contemporary dance music, giving one song the ability to appeal across many different musical genres or dance venues. Such remixes often include "featured" artists, adding new vocalists or musicians to the original mix. The remix is also widely used in hip-hop. An R&B remix usually has the same music as the original song but has added or altered verses that are rapped or sung by the featured artists. It usually contains some if not all of the original verses of the song, but they may be arranged in a different order.
