Many many things explode in the video for will.i.am's collaboration with Britney Spears: Cars, disco balls, speakers, bottles of booze. But we weren't really expecting subtlety from these two. "Scream and Shout" is a five-minute slab of club catharsis with a slick electro-percolating beat and a hilariously retardo Tears For Fears-jacking chorus. There's something else here we weren’t expecting: a sense of humor, especially from Britney. She cops a silly robo-British accent somewhere between bored-Madonna and Sleaze-3PO and drops a cold-stare "it's Britney bitch," continuing to turn what should've been a career-killing punchline into an I'm still here, fuckers statement of diva defiance. Keep bitchin', B.

Listen to "Scream & Shout":

“Youth Knows No Pain”

“Like on 'Youth Knows No Pain' — we are the ones that should demonstrate, because we can take it,” Likke Li said. “We can pierce ourselves, take Ecstasy, dance all night and still go to work at our McDonald's jobs.” Despite the hedonistic sentiment in the song, the Swedish singer also admitted in hindsight her youth had repercussions. “I remember when I was 18-19 and feeling that I know it all,” Li said. “I always feel that I know it all. But that song is about realizing you don’t, and reflecting, ‘Boy, if I only knew what would follow.’”
