Best crowd-sourced music videos: Weezer, Lily Allen and more

You're a clever bunch, you lot out there in Internetland. And rather attractive too, may we say. We're not the first to spot your potential -- pop stars including Cassius, Lily Allen, and Weezer have recruited the denizens of the Web to create user-generated music videos.

From a song that was entirely crowdsourced to an iPhone app that gives a new meaning to lip-synching, we present for your delight and delectation the best music videos to feature you lot singing alongside the stars.

Cassius -- I <3 U SO

You're nobody if you don't have an iPhone app these days. The video for I Love U So by French electro duo Cassius features a host of passers-by singing the haunting refrain, "Oh I love you so, but why I love you I never know," into a specially-made I <3 U SO app for the iPhone. The song appears on The Rawkers EP released this year on Ed Bangers Records. The video was directed by We Are From LA.

Chartjackers -- I've Got Nothing

The Chartjackers project set out to hijack the hit parade in aid of Children In Need in 2009. Four YouTube bloggers spent ten weeks crowd-sourcing an entire song, drawing the title, lyrics, melody, singers, band, production, cover art from the Web. The result was I've Got Nothing. Documented by a BBC Switch TV program, the project was aided by Busted and Fightstar's dreamy Charlie Simpson and Fame Academy vocal coaches David and Carrie Grant, and charted at number 36 in the UK singles countdown.

Sour -- Hibi No Neiro (Tone of Everyday)

Japanese trio Sour recruited their fans and their webcams for the video to Hibi No Neiro, or Tone of Everyday, from their Water Flavor EP. It was directed by Masashi Kawamura, Hal Kirkland, Magico Nakamura and Masayoshi Nakamura. The jaunty, noodly acoustic ditty is accompanied by a spellbinding human mosaic of drawings, cameras, raindrops, wheely chairs and intricately choreographed arm-waving. Ripped off but never bettered, if this doesn't make you grin like a loon then you have a heart of stone.

Feeder -- Just A Day

The infectious riff-rockin' of Feeder's Just A Day was accompanied by more fans with cams. But this was filmed way back in 2001, with the clips of fans rockin' out in their bedrooms pre-dating and presaging YouTube. The song reached number 12 and the video was a fixture on music TV channels for months. Whatever you think about pop-punk moppets bouncing around the place, we challenge you not to smile at the drumming baby.

Barenaked Ladies -- Sound of Your Voice

Zany Canucks Barenaked Ladies were one of the first bands to offer an album on a USB stick. In 2006 they turned to YouTube for the promo clip to yearning single Sound of Your Voice from the Barenaked Ladies Are Me album. Instead of fans, the video employs newly minted YouTube meme celebrities, including the Where The Heck is Matt? dancing guy, the Mentos scientists and the Numa Numa dude.

Weezer -- Pork and Beans

It was such a good idea that nerd-punk japesters Weezer nicked the idea for Pork and Beans from the Red album in 2008, raising things up a notch by bringing Tay 'Chocolate Rain' Zonday, Chris 'Leave Britney Alone' Crocker, the Numa Numa guy (again) and a legion of viral video legends into one truly epic clip.

Lily Allen -- The Fear (The People vs Lily Allen Video Remake)

The makers of Xbox karaoke game Lips wanted someone a bit lippy to help them promote the game, and who better than everyone's favourite ray of sunshine Lily Allen? Members of the public recorded this karaoke version of isn't-it-terrible-being-famous anthem The Fear from Lily's 2009 album It's Not Me, It's You.

Dubbledge -- Lips 2 Da Floor

Finally, it's Crave's all-time favourite YouTube mash-up of YouTubers gettin' proper mash-up. UK rappers London Zoo, Dubbledge and Mention provide the rhymes for Lips 2 Da Floor, a wickedly funny -- and wince-inducing -- collection of YouTube missteps, pratfalls and things that probabably seemed like a good idea at the time. We warn you: it's not for the faint-hearted. Now don't make us have to remind you about our socks -- serious.
