Bebe Rexha's potent hooks have livened up hip-hop, EDM and R&B smashes, and she's collaborated with emo-minded MC G-Eazy and party-country duo Florida Georgia Line. The chorus of David Guetta's star-studded “Hey Mama”, which she sings, sums up her songwriting style, which is defined by sky's-the-limit vocals and big vowel sounds; the Rihanna-sung hook for Eminem's “The Monster” shows how Rexha's input resonates even when she isn't on the mic.
