There have been 1383 UK chart single number 1s since 1952.
Development of "The Lazy Song" began while Bruno Mars, Philip Lawrence and Ari Levine were hanging around the studio and didn't feel like working. Mars wrote the song in collaboration with singer-songwriter K'naan and his production team The Smeezingtons, who also produced the track. 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. It was certified seven times platinum by the Recording Industry Association of America (RIAA), five times by the Australian Recording Industry Association (ARIA) and four times by Music Canada (MC), respectively. It was one of the best selling digital singles of 2011 with sales of 6.5 million copies.
