MUMBAI: Over the years, songs have served as catalysts for the transformation of cultural and political landscapes. Music has also set trends in fashion and dance while breaking convention and testing the boundaries of societies' accepted moral values.

Now lifestyle channel Discovery Travel & Living will profile the revolutionary music that left an indelible mark on the world in the new show Impact: Songs That Changed The World. the show airs every Sunday at 8:30 pm and Saturday at 4:30 pm.

Songs like Bob Marley's freedom anthem I Shot the Sheriff, Elvis Presley's brash and rebellious Heartbreak Hotel and Aretha Franklin's female empowerment mega-hit Respect represent milestones in the history of popular music. The show will feature interviews with recording artists, cultural and political pundits, religious leaders, radio and television commentators, musicologists, sociologists and music fans.

Discovery Travel & Living brand dierctor Aditya Tripathi says, "Impact: Songs That Changed The World presents fascinating stories of songs that played an instrumental role in major political, social and economic movements. The series highlights how music, whether pop, rock, country or rap, has a penetrating impact on people's lifestyles."

One episode features Maybellene which was sung by Chuck Berry. In the changing world of America in the mid 1950s, Chuck Berry's Maybellene was the heart and soul of an explosive new force known as rock 'n' roll. Ironically, at the age of 30, Chuck Berry became the creator of an exciting new soundtrack for teenagers who had emerged as a potent commercial force in the wake of a booming economy. Chuck Berry represented freedom, and the impact of his trend-setting Maybellene is still felt in popular music circles today.

Another episode shows how Heartbreak Hotel defined Elvis Presley and arguably became the first true rock 'n' roll record. It was a song of teenage angst, not the puppy love, and depicted the real, so-lonely-I-could-die variety. It established rock 'n' roll as an attitude as much as a musical style - brash, rebellious and sexually charged - and became the soundtrack for alienated youth.
