I was just searching this song "3OH!3 feat Katy Perry Starstrukk" in HD. The official youtube channel has only 360p. While searching through google and youtube, I came upon a simple user who has this video in 1080p. So my question is that while official channel does not have this video in 1080p so where this guy got that video. Are songs released on DVD in 1080p .. or bluray... Please guide me ..
