I think it is cute, upbeat and fun. There is nothing wrong with it. And for those who say it is a goyish tune. Think about MBD who’s song Yiddin everyone still sings and hums. That was a German march! So everyone from Country Yossi to MBD, has taken Goyish tunes and turned them into Yiddish hits!
It is a group of Yeshiva boys singing a Chanuka song. They are all dressed like OREOS, with their white shirts and black pants, there are no girls in the video, there is nothing non-kosher in the video, and it is even accapela so there is no musical instruments involved. Anyone can listen to it at any time. It is an informative song about Chanuka and it is fun to watch and fun to listen to. I don’t see any downside to it.
It is probably a good beat to walk to and exercise to. If you like this kind of music, go for it.
