YouTube has come to define the era of online video, so let's take a look at its most popular videos of all time. Our latest update has Justin Bieber still at number 1 with Baby, which was the first video to earn a half a billion views! Currently, Bieber and Eminem between them make up half of the top 10. Also of note is a music video by Jennifer Lopez called On The Floor ft. Pitbull, which has risen to number 3 with 400 million views in only 8 months.
We first did this list in August 2007, at which point Evolution of Dance by comedian Judson Laipply was number 1 with nearly 56 million views (it's now outside the top 10). The next update was September 2008, when Avril Lavigne's Girlfriend pop music video was number 1 with 103 million views. In January 2010, Charlie bit my finger - again ! was number 1, with 148 million views. By the beginning of January 2011, Justin Bieber was at number 1 with over 400 million views for Baby.
Kolaveri: What does it mean actually? kolaveri fever :p
'Kolaveri', a rage on the internet and elsewhere, is a highly popular slang among Tamil youth, normally used to silence a cranky person in a group.
It is among several Tamil words which youngsters use between themselves without implying actual meaning. Kolaveri, which means murderous rage, is now popular even in other parts of the country, thanks to the peppy song 'Why this kolaveri di?' from upcoming Tamil flick '3'.
The song is a rage among millions of students and youngsters, especially in social networking sites like Facebook and Twitter and video sharing site of You Tube. 'Yen indha kolaveri? (why this kolaveri)' can be heard in college campuses and other places where youngsters hang around in Tamil Nadu.
It is actually used to put off a cranky person in a group. The slang has been used by the makers of '3' to depict the anguish of a person who has just tasted rejection from the hands of a girl whom he liked.
The Internet was made for things like this. “Why this Kolaveri” sung by Tamil actor Dhanush has become the latest viral sensation to sweep across Indian cyberspace, getting almost one and a half million views since it was first uploaded on to youtube last week.

The droll exaggerated accent Dhanush employs as he sings “Why this kolaveri kolaveri kolaveri di” is an instant earworm and eminently singable. The lyrics are hilarious and helpfully come with subtitles so that we all know just how to pronounce “black-u” (Like the girls heart) and “white-u” (like her skin). Kolaveri – if you didn’t know before – roughly translates to mental torture. In between the singing, Dhanush makes helpful little comments like “rhythm correct” and at one point even employs auto tuner (think every recent Usher song you have heard) as he chants “one-two-three”
The music producer of the film “moondra” (three) that Kolaveri is a part of, Anirudh Ravichandar, told CNN IBN he had just mixed the music, when Dhanush walked in, heard it and just sang it impromptu. “Till date we have no lyric sheet for the song” he said, adding that it had taken them only 20 – 25 minutes to completely finish recording the song before he got the musicians in.
Before inventing the T-Pain Effect, the Atlanta rapper/producer played a crucial role in introducing Auto-Tune into hip-hop. Soon it created a ripple effect into pop music, which had previously experienced Auto-Tune in a big way via Cher’s “Believe” in 1998. The trend simmered when Jay-Z – disturbed by the countless number of rappers jumping on the Auto-Tune bandwagon — took it upon himself to declare the trend dead via his track “D.O.A.” (“Death of Auto-Tune”) on “Blueprint 3.” It just hasn’t been the same for T-Pain’s Auto-Tune-filled career since then.
“Buy You A Drank”
T-Pain Feat. Yung Joc
It’s only fair T-Pain holds a slot on our list, after all he did revive the trend in the 2000s. T-Pain showed the world the power of Auto-Tune with his Hot 100 No. 1 “Buy You a Drank (Shawty Snappin’).”
“Bed Intruder Song”
The Gregory Brothers & Antoine Dodson
With hundreds of millions of YouTube views, it’s fair to say that behind T-Pain, Auto-Tune the Newsmay be the most well-known example of the vocal effect. The Gregory Brothers, who are behind the Auto-Tune the News series, created 2010′s biggest viral sensation by Auto-Tuning Antoine Dodson’s heated TV rant about “hiding yo’ kids, hiding yo’ wife.”
“Believe”
Cher
Long before T-Pain brought Auto-Tune “back,” Cher — the ultimate musical chameleon — had mastered it and moved on. In late 1998, her “Believe” single, which featured her oft-impersonated Auto-Tuned vocals, hit the airwaves. Soon enough, the single made its 4-week reign at No. 1 on the Hot 100, going on to become one of the best-selling singles of all time (1.8 million physical copies, according to Nielsen SoundScan).
“Love Lockdown”
Kanye West
Kanye West’s fascination with Auto-Tune was anything but subtle on his 2008 breakup album, “808s & Heartbreak.” He traded his rhymes for sung vocal parts on the electropop meets R&B release — a departure he made clear on the album’s first single, the tribal-leaning “Love Lockdown”
“Woods”
Bon Iver
On his 2009 “Blood Bank” EP, Bon Iver followed up the sweet folk jams of debut “For Emma, Forever Ago” with… Auto-Tune? Bon Iver’s Justin Vernon proved that the vocal effect is not just for rappers, creating an especially haunting effect on his track “Woods,” which, in turn, inspired a rapper (Kanye West’s “Lost in the World”).
“Lollipop”
Lil Wayne
Lil Wayne backed up partner-in-crime T-Pain and stamped his co-sign on Auto-Tune by using the software in his Hot 100 No. 1 “Lollipop.”
“Blow”
Ke$ha
Ke$ha has heralded the pop return of obvious Auto-Tune in recent years, first with her debut single “TiK Tok” and most recently with “Blow,” whose chorus would certainly falter from a lack of Auto-Tune.
“One More Time”
Daft Punk
Daft Punk’s 2000 single “One More Time” is certainly not the French DJ duo’s only foray into Auto-Tune, but it might just be their best. The tuned and compressed vocals from DJ/producer Romanthony seem an almost natural fit alongside heavy dance beats on the “Discovery” single.
“Boom Boom Pow”
The Black Eyed Peas
No surprise here, as will.i.am will try (almost) anything once. The mega-successful pop group gave a nod to Auto-Tune with the Hot 100 No. 1 hit, “Boom Boom Pow.”
“Sensual Seduction”
Snoop Dogg
“Sensual Seduction” (unedited as “Sexual Eruption”) captures Snoop in a retro ’80s ‘fit, singing into a talk box. A perfect celebration to Auto-Tune.
