Pinkfonge had originally released previous versions of this song but it was the 2017 version of it that hit viral worldwide.

The famous 2016 recording was sung by Hope Segoine, then a 10-year-old Korean-American singer.

Produced by The Pinkfong Company, and Directed by Min Seok Kim, the song is extremely good for preschool children, who benefit from repetitive, predictable patterns, but for that same reason, the song is the reason that for adults have becomes annoyingly catchy.
Even myself, although not a fan of the song, perhaps because I'm a bit too old for it, once I hear that song, it tends to get stuck on repeat in my head for a very long time. This makes it highly irritating to me.
It's not a very sophisticated song, and it really doesn't need to be because it is geared for children who just wanna have fun.
This company has produced thousands of children children's songs, but this song became it's signature.

As an adult, I hate this song with a passion, but, if you have a toddler or a preschool child, it is actually a very good song for them in terms of learning and development things, in that regard I really recommend it, but I personally don't recommend it to any adult.
