We've always known Lykke Li is a badass. The Swedish songstress covers hip-hop songs with megaphones, dances like she doesn't give a fuck, and conveys an ever-present edge that sets her apart from the flock of other pop singers with big hooks and sexy voices. On "Get Some," from her sophomore release, Wounded Rhymes, that edge is sharper than ever. With pounding drums, menacing lyrics, and an unflinching delivery, this is her baddest-ass song to date.
