Beyoncé’s album titled with a single digit that includes “Love on Top” is 4.
Released in 2011, 4 was Beyoncé’s fourth studio album as a solo artist. Its title refers to the number four’s personal significance in her life: she was born on September 4, her mother’s birthday is January 4, and she married Jay-Z on April 4.
“Love on Top” became one of the album’s most recognizable songs. Its arrangement uses repeated key changes near the end, creating a progressively rising vocal climax. Other songs on 4 include “Run the World (Girls),” “Best Thing I Never Had,” and “Countdown.”
The album followed I Am... Sasha Fierce and preceded Beyoncé. Its musical style drew on R&B, pop, funk, soul, and earlier vocal-group traditions, giving the project a sound distinct from the more surprise-driven release strategy she later adopted.
