The Jonas Brothers were very big especially from 2007 to 2009. I remember every single girl in my school was a fan of theirs and especially during 2008 you couldn't go anywhere without hearing Burnin' Up being played on the radio at least once. You have to remember back then they were really only popular with very young kids we're talking 8 to 13 years olds and that was the age before social media so no one outside of that demographic would realize how ubiquitous they were. They sold over 17 million albums, they had a top five hit with Burnin' Up, they had a huge 3D concert film when those were still a thing.They were in one of the biggest DCOM franchises of all time. During their world tour they even enticed a riot and the police had to get involved it was that bad. Honestly I'm not surprised by the reaction this song is getting. It's a catchy pop tune in a time where that is relatively scare made by a band that incites a lot of nostalgia for a lot of people.
