Rihanna's single “We Found Love” stayed atop the Billboard Hot 100 for the final eight weeks of 2011.
The song, featuring Scottish producer Calvin Harris, became one of Rihanna's signature dance-pop hits. It first reached No. 1 in November 2011 and remained there for eight consecutive chart weeks through the end of the calendar year. Its reign continued into 2012 for two additional weeks, giving it 10 weeks at the top overall.
“We Found Love” was Rihanna's 11th Billboard Hot 100 No. 1 and her longest-running chart-topper at that point. The track's electronic production reflected the rapidly growing influence of dance music on mainstream pop in the early 2010s, while its emotionally conflicted lyrics contrasted with its euphoric club sound.
Readers sometimes remember “We Found Love” as an eight-week No. 1 for the entire run, but the precise distinction matters: eight of those weeks fell in 2011, and two more occurred in January 2012. It was also the longest-running single at No. 1 during 2011.
