Rihanna’s “Only Girl (In the World)” (2010) is a thumping dance-pop anthem that demands full attention from a lover. With its roaring Eurodance synths and Rihanna’s powerful voice declaring she wants to feel like the only girl in the world, the track is built for the clubs. It blasted to No. 1 on the Hot 100 and in many countries, kicking off Rihanna’s Loud era and winning a Grammy for its high-octane, feel-good rush of empowerment on the dance floor.
