Friday (Rebecca Black song)

"Friday" is the debut single by American singer Rebecca Black. It was written and produced by Los Angeles record producers Clarence Jey and Patrice Wilson. The song's music video was released on February 10, 2011; it was officially released as a single on streaming platforms on March 14, 2011. A teen pop song, "Friday" features Black singing about her daily morning routine and her excitement for the upcoming weekend. The song makes heavy use of auto-tune, and also includes a rap verse from Wilson, which was uncredited on the single.

Black was inspired to record a song with Jey and Wilson's music production company, ARK Music Factory, after seeing a high school classmate produce a music video with them. The music video for "Friday" caught a sudden surge of hits after Mystery Science Theater 3000 and RiffTrax comedian Michael J. Nelson called it "the worst video ever made" on Twitter and the song was featured on the Tosh.0 blog. The song's reception was highly negative, and it was parodied by numerous artists and comedians.

The original music video was removed from YouTube on June 16, 2011, due to legal disputes between ARK Music and Black. By then, it had already amassed more than 167 million views. The video was later re-uploaded to YouTube on September 16, 2011. The music video for the song is one of the most disliked YouTube videos of all time. Since the growth in popularity of the song and video, there have been numerous parody videos and remixes. On February 10, 2021, to commemorate the song's tenth anniversary, Black released an official hyperpop remix featuring 3OH!3, Big Freedia and Dorian Electra to more positive reviews.
