                Music
              Due
                  to its diversity, popular music in the United States today
                  challenges simple description. The history of popular music
                  in the 1970s and '80s is basically that of rock music which
                  has grown to include hundreds of musical styles. New styles
                  such as folk, salsa, new wave, funk, reggae, heavy metal, acid
                  rock, punk rock, rap, hip hop, acid jazz and world music have
                  developed. Country rock, a fusion of country and western and
                  rock 'n' roll, grew popular in the 1970s.
               A blend
                  of rhythm and blues and gospel music came to be known as soul.
                  Disco, a repetitive dance music, and rap music are direct descendants.
                  Rap developed in the mid-1970s among African-American and Hispanic
                  performers in New York City. It generally consists of chanted,
                  often improvised, street poetry usually accompanied by disco
                  or funk music. The 1990s saw the birth of alternative music
                  or grunge. Techno, a style of dance music that gained popularity
                  in the 1990s, combines computer-generated, disco like rhythms
                  with digital samples.
              In contemporary
                  music, there is a strong crossover phenomenon. Cultural influences
                  are much more readily available. The trend is not towards one
                  big homogeneous style, but rather an interesting meeting of
                  different influences in projects here and there. Whereas in
                  the past jazz, blues and country all came out of the roots
                  of black society and Appalachia, nowadays there are influences
                  from farther away. Musicians have become much more globally
                  aware of other kinds of music. A whole genre called "world
                  music," a sort of mix of ethnic music adapted to modern
                  western styles, has developed. It includes any ethnic music
                  that isn't big enough to have its own category.
              Two genres,
                  in particular, have exerted an extraordinary hold for the past
                  two decades or so -- rap and its close cousin, hip-hop. Born
                  of inner-city poverty rap replaces sung melodies with rhythmically
                  punchy, mostly rhymed recitation set to an insistent beat.
                  Hip-hop uses many of the same features, but it is a more dance-driven,
                  rather than message-driven, phenomenon. Both styles have African-American
                  roots, but have been quickly embraced by white performers and
                  can be encountered today just about everywhere and in just
                  about any circumstance.
