Death Metal Monday

Oh, and in case you didn't know where this came from - it's the most popular Worst Song in history.

A song by a 13-year-old American teenager has gone viral on the internet after being widely described as the worst one ever recorded.

Rebecca Black's pop song called Friday has been viewed on YouTube more than 29 million times.

It has trended on Twitter and been the subject of huge online comment and discussion.

That's mainly because it's been derided by millions of people for what they say are its awful lyrics.

Ones like "yesterday was Thursday Thursday, today it is Friday Friday", "gotta get down to the bus stop, gotta get my bus, i see my friends" and "we we we so excited, we so excited".

People have been quick to criticize the song for more than just its words.

The teenager's heavily auto tuned singing and video have also been labeled as terrible.
