The 1970s saw the division of rock into different divisions beyond the general categories of hard rock and mellow rock. Disco became popular and rock blended with reggae, which came from Jamaica around 1972, and is a mix of rock, soul, and other rhythms. Other styles that came out of the 70s were punk rock, bubblegum music, and heavy metal rock. Led Zeppelin was very popular during this time. Their most famous song was "Stairway To Heaven."
