Which 2008 Beyoncé song became her fifth US Billboard Hot 100 number-one single?

“Single Ladies (Put a Ring on It)” became Beyoncé’s fifth US Billboard Hot 100 number-one single in 2008.

The song was released in 2008 as a single from Beyoncé’s third studio album, I Am... Sasha Fierce. Its lyrics focus on commitment and independence, while its instantly recognizable rhythm and repeated hook helped make it a global pop-culture phenomenon.

The black-and-white music video, directed by Jake Nava, features Beyoncé and two dancers performing tightly synchronized choreography. The video’s dance became especially influential, with its central hand and hip movements widely imitated in popular culture.

“Single Ladies” followed Beyoncé’s earlier US number-one solo singles “Crazy in Love,” “Baby Boy,” “Irreplaceable,” and “Check on It.” It is distinct from “Halo,” another major hit from the same album, which reached number five on the US Hot 100 rather than number one.
