"
Single Ladies (Put a Ring on It)" is a
dance-pop and
R&B song from American singer
Beyoncé's third studio album,
I Am... Sasha Fierce (2008).
Columbia Records released "Single Ladies" as a
single on October 13, 2008 alongside "
If I Were a Boy", showcasing the contrast between Beyoncé and her aggressive onstage
alter ego Sasha Fierce. It explores men's unwillingness to
propose or commit. In the song, the female protagonist is in a club to celebrate her single status.
