The payment covered one half or less of the production costs of the music video, and Black's family could have paid nothing in exchange for giving up all rights to the song. Black chose "Friday", as "the other song was about adult love – I haven't experienced that yet. I felt like it was my personality in that song."

"Friday" co-writer Patrice Wilson explained that "I wrote the lyrics on a Thursday night going into a Friday. I was writing different songs all night and was like, 'Wow, I've been up a long time and it's Friday.' And I was like, wow, it is Friday!"
