`::::::::::Another reference (also by YouTube  ``indisputably confirmed legit YT data, not stuff calculated/estimated/claimed by external agencies`` !) states the following:PSY already holds the record for the most viewed video of all time  Gangnam Style now has an incredible 1.5 billion views  but now he also set the record for the most views ever in a single day with the over 38 million ``Gentleman`` achieved on April 14th.[PSY's 'Gentleman' Raises the Bar]And another more recent, this one from June 2, 2014 (in case anyone should say, ``uhh, the reference is from 2013, how do we know a different video has not broken the record!?!?``):Psy’s follow-up to “Gangnam,” another K-Pop banger called “Gentleman,” set the record for the most views ever in a single day (38 million on April 14, 2013). 대~박! (That’s Korean for “holy cow!”)Interestingly, the last reference includes a link on the page for most viewed videos which sorts search results by view count and apparently is for ``all time`` except for whatever reason a few of the videos on the article list are missing from the YouTube results  ``On the Floor``, ``Bad Romance``, ``Never Say Never``, ``Super Bass``  I'm unsure why after briefly glancing and will try to determine an explanation.     `
