If you made a hipster-rap bonus baby in a laboratory, you couldn't do much better than Theophilus London. The 23-year-old Trinidad- born Brooklyn MC's neo-retro hip-hop mashes up TV on the Radio's vocal cadences, old-school break-dance beats and the forlorn melodic tug of a Smiths fan (he dropped This Charming Mixtape in 2009). "Why Even Try" recalls Tom Tom Club's electro-bubblegum classic "Genius of Love," but place-holder lyrics—“ "Back on the road again/Hitting Paris on a 10," from "All Around the World"—show that even in hipster rap, you need to rock the words, too.

“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.’”
