Rebecca Black's 'Saturday' Follows 'Friday' Onto Hot 100

The young viral sensation returns at No. 55 with her second Hot 100 hit

Rebecca Black scores her second entry on the Billboard Hot 100, as "Saturday" debuts at No. 55 following its first full week of U.S.-based sales and streams. The teen famously charted in 2011 with her debut single and video "Friday."

"Saturday" accumulated 3.3 million streams in the U.S. last week (Dec. 9-15), according to Nielsen BDS, entirely from YouTube, spurring its No. 12 debut on the Streaming Songs chart. It also sold 3,000 downloads its first full week of availability, according to Nielsen SoundScan.

The song that became the catalyst for Black's meteoric viral rise, "Friday," has sold 442,000 to date since it stormed onto YouTube in 2011. The bow of "Saturday" on the Hot 100 bests the No. 58 peak of "Friday" the week of April 2011, although there's a key caveat: that was before YouTube data began factoring into the Hot 100's weekly tabulation as of this March.

For "Saturday," Black collaborated with Dave Days, an alternative/rock musician well-known on YouTube for both his original and cover songs. Days boasts more than 1.5 million subscribers to his YouTube channel, which has drawn more than 340 million views. (Among his other collaborators: Miley Cyrus.) 

"Saturday" was created without ARK Music Factory, the production company which helped bring "Friday" to fruition, although the new track contains plenty of references to her previous hit single. The first line, "2 p.m., getting out of my bed, trying to get Friday out of my head," is the first of several cheeky allusions. Video references also borrow from "Friday," including party-goers writing "fun, fun, fun" on a passed-out person's face with a Sharpie and Black's cereal bowl labeled "gotta have my bowl."

(And, following "Friday" in 2011 and "Saturday" in 2013, perhaps, at this rate, we can look forward to Black charting with "Sunday" sometime in 2015.)
