quote from article
"Not that she's necessarily singing the praises of the song, which was part of a $2,000 package her mother paid to Ark Music Factory, an L.A.-based vanity production company for aspiring teen singers.
The producers offered her two songs, and she settled on "Friday" because, she told the Daily Beast, "The other song was about adult love -- I haven't experienced that yet. 'Friday' is about hanging out with friends, having fun. I felt like it was my personality in that song.""
The point is, this is just some music studio that will let anyone come in and make a couple of music videos for 2k. This was perhaps not meant to be taken seriously.
