But before you grown-ups write it off as just something that young people are listening to, watch the latest "Kids React" video. It's a handy reminder that kids don't uniformly go for the popular stuff.
In fact, a few of the youngsters watching the "All About That Bass" video are doing it for the first time – and they seem a little embarrassed by it all. (Key reaction: "What is this even about?")
What's more, some of the young minds listening to this song aren't just hearing a dance beat. Some are hearing a positive message about acceptance and the human body.
Others, however, just do not see the appeal. One kid, in his bafflement, lays out a fundamental truth about pop music. "It's one of those songs that talks about fat butts," he says. "For some reason, everyone likes to hear about butts."
