The worst song ever?

Justin Bieber, move aside.

Here comes Justine Bieber, a 13-year-old who's been heavily criticised online for singing the "world's worst-ever song" may be having the last laugh.

For the benefit of those in the dark, teenager Rebecca Black recently released a song, Friday, that has become a viral hit over the web after appearing on a Tosh.0 blog post titled "Songwriting Isn't for Everyone".

However, the Californian, who has been trending on Twitter for the past week, has received ridicule for her performance of the song, which was written by Clarence Jey and Patrice Wilson.

But as views of the much-mocked video jumped from 3,000 to 18 million in just a week, something about this oh-so-wrong song must be oh-so-right.

Lambasted by critics as having overly simplified lyrics like "tomorrow is Saturday/ And Sunday comes afterwards/ I don't want this weekend to end", the song describes Black's typical Friday, when she goes to school and meets her friends at night.

Reviewers on BNET and CNN also noted that the rap break from the considerably older rapper was "creepy".

And to think that all Black wanted to do with the song was to let her friends listen to her sing and, perhaps, gain a few fans.

Even Black's idol, Bieber, didn't appear impressed, given his post on Twitter, "sunday comes after saturday? weird".

Ironically dubbed "the new Justin Bieber", Black actually has a fan in former American Idol judge Simon Cowell.

The X Factor creator told PEOPLE, "I want to meet her. Anyone who can create this much controversy within a week, I want to meet. I love people like that."

To dispel speculation that she had to rely on AutoTune to record the song, Black is planning to release an acoustic version of it.

According to Forbes.com, Friday has amassed a staggering 2 million downloads since hitting the iTunes store last Monday.

Friday debuted at number 33 on the New Zealand Singles Chart on Monday.
