"The Lazy Song" is a song by American singer-songwriter Bruno Mars for his debut studio album Doo-Wops & Hooligans (2010). It was serviced to contemporary hit radios in the United States on February 15, 2011, as the album's third single by Atlantic and Elektra. Development of "The Lazy Song" began while Mars, Philip Lawrence and Ari Levine were hanging around the studio and didn't feel like working. The trio, produced the track under their alias, the Smeezingtons, and wrote the song in collaboration with singer-songwriter K'naan. Musically, "The Lazy Song" has been described as borrowing "heavily from roots reggae" and has been compared to the reggae style of Jason Mraz, while lyrically it is an anthem to laziness.
