This is a long shot. I can't actually remember anything about how the song goes other than its as if they sing in low volume and then increases.. it's dorky so whatever genre that would be. It's 2 white guys in white tshirts and blue jeans running in a field of some sort or grassy patch, i think there was also a wooden fence they were running along. They sing in English, are in their mid to late 20's and it's super dorky and funny to me. I think they might be brothers. It almost sounds like they sing in slow motion but not really. Circa 2010 ish.
thx
