Which Beyoncé song became her first solo song to win the Grammy for Song of the Year?

“Single Ladies (Put a Ring on It)” became Beyoncé’s first solo song to win the Grammy for Song of the Year.

The song was released in 2008 as a single from I Am... Sasha Fierce. Its theme centers on commitment and marriage, while its sharply defined dance routine helped make the music video a major part of the song’s cultural impact.

At the 52nd Grammy Awards in 2010, the song won Song of the Year, Best Female R&B Vocal Performance, and Best R&B Song. The songwriting award recognizes the composition, rather than simply the recording or video.

Beyoncé had already received Grammys as a member of Destiny’s Child. The question concerns her solo songwriting award, which is why earlier group victories do not change the answer.
