Why would anyone dislike this video?

Well ... Her voice is monotonous; she drones on and on and, from my point of view, she's monotonic without relief; how she needs a break 😕. Whilst the song itself is hardly entertaining, I can see how it gets 3.2 million dislikes; which hardly matters because by the time she's paid from Google Ad's (and her own sponsors) she'll still be laughing all the way to the bank :)
