I do agree that this video can be really good for some kid in a public school out in the midwest and many others who need to hear that judaism is cool and then they might begin to discover it for themselves.
That being said, forget for a second whether or not Hashem is smiling at the song or not. This is chanuka, right? What are we celebrating on chanuka, besides the face level of the oil burning for 8 days? The real intense celebration of chanuka is of the victory of pure kedusha over anything that was touched by the goyim. The whole reason the maccabees even found that one jug of pure oil is because they searched and searched and searched; they could not entertain the thought that they would light the menorah for Hashem with something that was touched (just touched!) by the goyim. Now I understand that this video may end up helping some irreligious people, but coming to the bottom line – really what would the maccabees have thought of the song? How about the hellenists?
Remember what chanukah is actually about before you stamp your seal of approval.
