Skrillex teamed up with seasoned film composer/ex-Red Hot Chili Peppers drummer Cliff Martinez to score Spring Breakers, in which Selena Gomez and Vanessa Hudgens go wild and James Franco plays a rapper-criminal. Along with previously released songs by Gucci Mane, Meek Mill and Ellie Goulding (and one where Franco flows in character),  Skrillex has embedded an EP's worth of new material (two solo tracks, three with Martinez). It's refined, minimalist, often quite lovely and even chiller than Trent Reznor's Social Network score. He could have a second career in Hollywood once the whole dubstep thing dries up.

“Ambling Alp”

The "Ambling Alp" was the nickname of the six-and-a-half-foot-tall Primo Carnera. Though the song is named after the Italian-born 1930s heavyweight champion, Yeasayer are actually paying tribute to boxing legend Joe Louis with this first-person psychedelic dance-rock tune. “I was always interested in writing a song that had boxing mythology in it,” Yeasayer’s Chris Keating said. “It’s pretty fascinating: There were so many amazing characters, and it was so closely entwined with 20th century history.” Yeaseyer also invokes German champ Max Schmeling and hints at the historical significance placed on the historic bouts between the Nazi-era boxer and the African-American Louis.
