- Race: Rock and roll was often associated with black musicians and African-American culture, which made some white listeners uncomfortable.
- Lyrics: Rock and roll songs often dealt with taboo subjects such as sex, drugs, and rebellion, which offended many people.
- Volume: Rock and roll music was often played at loud volumes, which could be disruptive to others.
- Dancing: Rock and roll music was often associated with energetic and suggestive dancing, which was seen as inappropriate by some people.
These factors combined to make rock and roll music a controversial genre in the 1950s and 1960s. However, rock and roll eventually became mainstream and is now one of the most popular music genres in the world.
