This 23-year-old Londoner is being hailed as "the U.K.'s answer to Lady Gaga," which might say more about the U.K.'s desire to answer to Lady Gaga than it does about Jessica Ellen Cornish. She's got a brash, broad voice and a be-yourself message. But Jessie is less show-stealing diva than impersonal pop technician (she co-wrote Miley Cyrus' "Party in the USA"). Her debut sounds like a collection of demos for other singers - Natasha Bedingfield on the down-to-earth "Price Tag," Katy Perry on the Dr. Luke-assisted "Abracadabra," Rihanna on the gender-flipping "Do It Like a Dude." It's well-meaning, well-crafted and confused. Sometimes versatility can be a vice.

Jessie J Makes Her Big American Debut on 'SNL'

“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.’”
