Stormzy's infectious single Vossi Bop was the most-watched music video of 2019 in the UK, YouTube has revealed. Based around a viral dance craze, the video sees the star rapping on Westminster Bridge and features a cameo from Idris Elba. Sam Smith and Normani's Dancing With A Stranger was the second-biggest video. Billie Eilish's Bad Guy came third. Outside the UK, Latin music dominated, accounting for all of YouTube's top five music videos. Top of the list is Daddy Yankee's Con Calma - which interpolates Snow's 1990s rap classic Informer; while electro-flamenco singer Rosalía takes second place with the earworm groove of Con Altura. It's the third year in a row that a Latin song has topped YouTube's global chart. In 2018, the honour went to Nio García's Te Boté; while in 2017, it was Luis Fonsi and Daddy Yankee's Despacito (which is the most-viewed video in the site's history, with 6.5bn views). The figures reflect Latin America's increasing importance to the music industry: It's the world's fastest-growing music market - revenues increased by 16.8% last year, with Brazil the largest contributor. Without any doubt, there was always huge music consumption in Brazil - it's a country that truly has music at its heart - but, due to copyright infringement, this was never recognised," said Afo Verde, chairman of Sony Music Latin Iberia, earlier this year. "When consumption began to take the form of streaming, the results were impressive." "I think it has been a sleeping giant for years and years, and the reality is that it's a country with more than 200 million people. And it's a country that loves music," added Jesus López, chairman of Universal Music Latin America. However, the spectre of piracy still looms over the market. It's notable that Latin artists thrive on YouTube, an advertising-supported platform, but have a lesser impact on services like Spotify and Apple, which generate larger revenues through monthly subscriptions. There have also been accusations that record labels in South America are "buying" views on YouTube to boost their artists' profiles. Both Spotify and Apple Music released their own most-streamed charts this week, and artists like Daddy Yankee were conspicuously absent; with Western stars like Camila Cabello, Lil Nas X and Post Malone populating the countdown. You can compare the various charts below:

Meanwhile, Joel Corry's sad-banger Sorry broke the record for the most Shazams in a single day. A total of 41,000 people looked the song up after it featured in an episode of ITV 2's Love Island on 24 July. "My phone went into meltdown when it happened," the producer said at the time. "It's got everyone talking, and helped launch the single up the Official Charts. I'm just buzzing everyone is loving Sorry!"
