Rhythmic contemporary, also known as rhythmic top 40, rhythmic contemporary hit radio or rhythmic crossover, is a music radio format that includes a mix of EDM, upbeat rhythmic pop, hip-hop and R B hits. Rhythmic contemporary rarely uses rock music or country music in its airplay, but it may occasionally use a reggae, Latin, reggaeton, or a Christian/gospel hit. Essentially the format is a cross between Top 40/Mainstream radio and urban contemporary radio.
