Mark Ronson and Bruno Mars' 'Uptown Funk' is a masterclass in modern funk, but it was a nightmare to record. The song took seven months to complete, with Ronson reportedly collapsing in a restaurant from the stress of trying to get the guitar part right. They went through over 80 takes of the guitar riff alone. The song heavily pays tribute to the 'Minneapolis Sound' of the early 80s (Prince, The Time). After its release, the band The Gap Band was added to the songwriting credits due to similarities with their hit 'Oops Up Side Your Head.' The song spent 14 weeks at number one on the Billboard Hot 100 and won two Grammy Awards. Its music video has surpassed 5 billion views, making it one of the most-watched videos in internet history.
