Not all hit singles are produced by pop artists. They're also produced by artists from many other genres like country music singers Carrie Underwood and Taylor Swift, rock groups Radiohead and Foo Fighters, folk singers Bob Dylan and Mumford & Sons, singer-songwriters Elton John and Ed Sheeran, contemporary R&B and soul music artists Beyonce and Adele, dance-music artists Daft Punk and Skrillex, and hip hop artists and rappers Kanye West and Eminem. Artists like these produce hit singles by writing songs that follow the pop-music formula but include elements of their own genre, and by doing this they can create their own unique style of pop music. Look at the list of best-selling artists below and notice how many have experience in more than one genre. It's artists like these who are most likely to create new styles of pop music in the future.
