R&B is often said to be an umbrella term for various genres of music which include blues music, jazz music, gospel music, soul music and more recently a bit of rap as well. It is, along with rap, gospel and hip hop, one of the genres of music pioneered by the African-American communities. The old love songs were slower while the newer lot tend to be faster.
