In his second full-length effort What Do They Know? Egor Krid smartly balances his hip-hop roots with the pop/R&B flavours that bolstered his debut The Bachelor. Facing any doubters out there, he declares himself a "rapper" on the title track, a swaggering opus laid over brooding, temperamental electronics. Elsewhere, smooth-flowing alternative R&B tones temper hip-hop beats and brash rants—while gloomy, low-key warm-ups set up catchy sing-along refrains. MOLLY also lends her sensual, raspy vocals in the duet “If You Don’t Love Me”, a radio-ready pop anthem tinged with synths and electric guitar.
