Whose hit song is "The Lazy Song"?

“The Lazy Song” is a hit song by Bruno Mars. It was released as the third single from his 2010 debut studio album, Doo-Wops & Hooligans, and became one of his signature early-2010s songs.

The track presents a deliberately carefree fantasy of staying in bed, ignoring responsibilities, and doing absolutely nothing. Mars co-wrote it with Philip Lawrence, Ari Levine, and K'naan, while production came from the Smeezingtons, Mars's songwriting and production partnership with Lawrence and Levine.

The single was released to radio in February 2011 and became a major international success. In the United States, it reached No. 4 on the Billboard Hot 100; it also topped charts in several countries, including the United Kingdom. Its memorable music video, filmed as a continuous shot, features Mars performing with a group of dancers wearing monkey masks.

A common mix-up is confusing the song's performer with its co-writers or producers. Although several musicians helped create it, Bruno Mars is the credited lead artist and vocalist—the canonical answer a quizmaster is looking for.
