No, it is not Gurbani Kirtan. Neither is it claimed to be one.
Here is the descritption from the site "this is a devtional sng by bitti describing a historic when some brave men of Guru Gobind Singh ji ran away and came back from battle. tey were cursed n humilated by the ladies of household for showinkhalsa, back in battle"
This clearly states that it is a devotional "song" . ...some thing similar to Dhadhi Jathas ways of telling stories.
