Themes and lyrics
Music can be used to express political views and opinions, and to tell stories about political events. For example, the song "Blowin' in the Wind" by Bob Dylan is a protest song about the civil rights movement, while the song "Imagine" by John Lennon is a call for world peace.
Sponsorship and funding
Political parties and organizations often use music to promote their causes and raise funds. For example, the Republican Party has used the song "Born in the USA" by Bruce Springsteen as a campaign theme song, while the Democratic Party has used the song "Happy Days Are Here Again" by Franklin D. Roosevelt as a theme song.
Censorship and suppression
Governments can use censorship and suppression to control what kind of music is available to their citizens. For example, the Soviet Union banned rock and roll music because it was considered to be a threat to the state.
Music as a form of resistance
Music can be used as a form of resistance against political oppression. For example, the song "We Shall Overcome" was used as a protest song during the civil rights movement, and the song "The Times They Are a-Changin'" by Bob Dylan was used as a protest song against the Vietnam War.
