This is just a short two-minute music video as part of the very long running "Minna no Uta" program, where different musicians perform child-friendly songs set to animation produced by different animators -- something that has been literally going on for decades. And, as one might expect, the results are always of varying quality.
You know what this reminds me of? Does anyone out there remember the animutation "Irrational Exuberance" for the Green Leaves video "Yatta!"? Some of the animation bits remind me of that, as well as the singers. Maybe I'm imagining it, but the sound is the same.
That being said...this is nothing like the gloriousness of "Irrational Exuberance". This is, instead, just another sub-par entry in the long list of sub-par "Minna no Uta" videos that are out there. The song is peppy and simple enough, but the animation has the same level of quality you would expect to see some flash thing an intern throws together in a day.
