YouTube on Thursday began publishing a chart that tracks top music videos at the popular Google-owned website. A YouTube 100 chart online at youtube.com/music will be updated weekly based on the popularity of videos whether works are amateur or professional, according to YouTube product manager Chris LaRosa. "On the Floor" by singer Jennifer Lopez was atop the inaugural list followed by "Judas" by pop queen Lady Gaga and "E.T." by musician Katy Perry.
"Not only does the YouTube 100 give props when fans make original videos for popular songs, it also captures YouTube's one-of-a-kind musical diversity," LaRosa said. "YouTube users get into music as fans and original musicians, and our new chart gives the community a better way to find the most engaging music on YouTube."
