When you think Justin Bieber, you think death metal, right? Ok, maybe not, but Bieber, Rebecca Black, the Jonas Brothers and other pop artists have been given the death metal treatment in creative videos posted on YouTube.

Our friends at Loudwire have put together a list of the 10 Best Death Metal Makeovers of Pop Songs, and Bieber's 'Baby' tops the list. The new version was recorded by Andy Rehfeldt, who turns the song into a scary rock tune with an angry, growling chorus, "Baby, baby, baby, no!" The metal rendition is matched to a live video of Bieber performing the track, creating one of the oddest visuals we've ever seen.

One of the most hilarious death metal songs on the list is the Rebecca Black cover. The new 'Friday' features rapid-fire drums and barely-coherent screaming about eating cereal and catching the bus. It's almost as brutally entertaining as the original.

It's equally funny to see demonic vocals coming from the mouths of the Jonas Brothers on the death metal version of 'Paranoid.' Other gems in the Top 10 include recordings of Justin Timberlake's 'Cry Me a River,' Rihanna's 'Disturbia,' and Celine Dion's epic 'Titanic' theme, 'My Heart Will Go On.'
