The Beatles revolutionized rock music in the 1960s and continue to influence generations of musicians. They skyrocketed to fame with hits like "I Want to Hold Your Hand" in 1964. Beyond their iconic music, the Beatles also influenced fashion and counterculture trends with their long hair and style. However, their lyrics and messages were also dangerously influential, as Charles Manson cited their songs as inspiration for his cult and crimes. Overall, the Beatles made an immense impact through both their music and broader cultural influence that still resonates today.
