Worth noting: There are now three components that make up the Hot 100 now. YouTube will be the lowest-weighted component, behind sales (#1) and radio play (#2)
It really worked for them when the album came out. It makes no sense now.
Final Edit: After looking at the whole Hot 100, this youtube thing screws with the format way too much. Songs jumping by 50-60 places week by week, and songs that don't have quite the same video views dropping 20 to 30 places week by week. After viewing this entire week's chart as a whole, I must say I'm not a fan of this change. I mean if the youtube chart has slightly less weight it would be good.
Yeaaa. Well The Harlem Shake has a lot to do with this, as Billboard, says:
"Billboard is now incorporating all official videos on YouTube captured by Nielsen’s streaming measurement, including Vevo on YouTube, and user-generated clips that utilize authorized audio into the Hot 100 and the Hot 100 formula-based genre chart."
Meaning if I use a Mumford and Sons song audio clip in a video I do and it's authorized by the label, then it counts as a hit for Mumford and Sons, even if it's like 20 seconds. So "The Harlem Shake" is #1: A) Because it actually did sell after last week. B) Because it was averaging about 4,000 videos a day using that 30 second clip. It makes sense, but I still don't like it.
