In the past year, Demi Lovato faced rehab and lost her role on a Disney Channel sitcom, her princess-next-door image shattered. On her third LP, her newfound vulnerability sometimes makes for good songs: "Would it make you feel better to watch me while I bleed?" she challenges an ex (or a tabloid-fixated public) on the tear-jerker ballad "Skyscraper," her voice becoming a sinister whisper. But Unbroken is mostly sunshine and slumber-party hooks, complete with reggae doo-wop ("You're My Only Shorty") and Lovato's ditzy seductress act on "All Night Long." She's grown into her voice. Now, if only her music would grow up too.

“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.
