Teenager Justin Bieber had four of the top 10 most-watched music videos in the world on YouTube in 2010, with "Baby" taking claiming the top spot at more than 400 million views, YouTube said on Monday.

The 16 year-old Canadian, who was first discovered in 2008 by posting home videos on YouTube, also saw "Never Say Never," "Never Let You Go" and "Somebody to Love Remix" make the most-watched videos from major music labels for 2010.

A young Alabama man giving an impassioned TV news interview about a local crime spree became the most-watched YouTube entry outside those produced by major music labels.

"Bed Intruder Song" -- a remix of the words by Antoine Dodson, 24, set to a song by New York musicians Evan and Michael Gregory -- was viewed 60 million times around the world. The song also entered the iTune charts and the revenue helped Dodson buy a new house.

Other YouTube favorites outside big names in music included a parody of singer Ke$ha's hit "Tik Tok" called "Key of Awesome #13", and home video of 13 year-old Greyson Chance singing his version of Lady Gaga's "Paparazzi" at a school recital.

"YouTube has become the world's town square -- a place where culture is created and shared," said Mia Quagliarello, YouTube community manager.

"It's a sign of YouTube's growing importance as a platform for content creation that six of the top 10 most-watched videos globally were made-for-YouTube originals."

YouTube, which is owned by Google, said that more than 13 million hours of video were uploaded to the video-sharing website in 2010 and there were more than 700 billion playbacks.
