Last week YouTube launched its Top 100 chart for music. It basically combines official videos from the likes of Lady Gaga and Jessie J. along with clips that have gone viral after being uploaded by users.

The chart (which is found on YouTube’s music page) is updated weekly, and the data is going to be stored. So, those of you who are up for tracking trends will have it made.

Right now, the chart offers no real surprises – Jennifer Lopez s at number 1 with “On The Floor”, Lady Gaga is at number 2 with “Judas”, Bruno Mars is at number 3 with “The Lazy Song”… and Rebecca Black is at number 10 with “Friday”.

Yeah, sure. As if she were going to have another hit song anytime soon…
