If you haven't heard this song yet, you're lucky. It's absolutely terrible....well, maybe I'm being a little harsh, considering this girl is only 13 years old.

However, Rebecca Black is apparently turning what some are calling the “worst song ever” into huge profits.

Forbes writer Chris Barth recently took a look at the digital sales and video streams for her now infamous (but admittedly catchy) song ‘Friday.’ Thus far, the video has over 30 million streams on YouTube, which has apparently translated into an estimated $20,000 — a big profit, considering Black’s mother paid Ark Music Factory a little over $2,000 for two songs and the ‘Friday’ video.

‘Friday’ is also sitting pretty on the iTunes singles charts, and can be purchased on Amazon.com, ArkMusicFactory.com, among other sites. With those combined digital sales (the report estimates that ‘Friday’ has been downloaded a few hundred thousand times on iTunes), Black stands to make a serious dent in her bank account. (Billboard.com says she’s making roughly $27,000 per week from track sales.)

Personally, I'm a huge fan of Conan O'Brien's rendition of the song. Watch the video below and see how Rebecca ripped Conan off!
