#13: “Physical” by Olivia Newton-John
Olivia Newton-John’s 1981 hit Physical sparked controversy with its suggestive lyrics and provocative music video. Some radio stations banned it due to its overtly sexual themes, while the video, which featured a same-sex couple, further fueled debates.

Despite the backlash, the song skyrocketed to success, spending ten weeks at No. 1 on the Billboard Hot 100. Its catchy beat and bold message helped redefine Newton-John’s image from a wholesome pop star to a confident, boundary-pushing artist.
