Ben Franklin had his lightning bolt. Newton had his apple. For Wiz Khalifa, the aha! moment must have come when he realized the words "green," "blow," "rollin' " and "paper" all applied to both marijuana and money. "Some say it's a problem/Blowin' my greens/Not savin' my collards," he raps on his hotly anticipated major-label debut. (Spoiler alert: He doesn't agree that it's a problem.)

On Rolling Papers, Khalifa, the 23-year-old Pittsburgh rhymer responsible for the jersey-waving hit "Black and Yellow," manages to give life to those kinds of cash-gorged perma-baked clichés by warmly luxuriating in the space between pop's fresh-faced exuberance and hip-hop's easy arrogance - between skater and playa, Bieber and Biggie. This is a guy who can effortlessly segue from the ominous G-funk whir of "On My Level" to the adorably crushed-out R&B crooning of "Roll Up."

Khalifa doesn't record with big-name hip-hop cameos (unless Too Short and Curren$y count as big names). Stargate (the Norwegian hitmakers behind "Black and Yellow") and Pittsburgh homey E Dan give tracks like "Wake Up" and "Star of the Show" a warm, lush synth-gauze that lends lines such as "Got money, minor league turn major/Got money, white people turn neighbors" a surreal joyousness. Which is exactly the point: Khalifa hustled for years to get his big break, suffering record-label indignities, releasing mixtapes and using Twitter to build a following. When he raps, "I don't wanna wake up," on "Wake Up," you can't help but hope his dream lasts a while.

“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.
