Icona Pop’s debut album is engineered to attract a second lightning strike. There’s a lot of shout-singing in unison and reckless party girl credos (“You and I live/Don’t learn” on “We Got the World”) that defined the duo’s massive international hit “I Love It,” and it’s hard to tell one song from the next. But there’s an earnestness to Caroline Hjelt and Aino Jawo’s freeloading hedonism that makes them more Hannah wilding out on HBO’s “Girls” (the synch that made “I Love It” spike) than Ke$ha getting slizzered. “Girlfriend,” a crafty Stargate-produced interpolation of 2Pac’s “Me and My Girlfriend,” sums it up nicely: We’re besties, we’re raging, get used to it. What the ladies lack in vocal virtuosity or diversity, they certainly make up for in charm.
