Mindless Behavior’s swaggering pop mixes bouncy electronic beats with smooth R&B and plenty of street-smart strut. On #OfficialMBMusic, the Los Angeles group perfect their radio-friendly formula by layering their soulful voices over rasping drum machines, and they specialize in catchy hooks that slither in your ear and tickle the brain’s pleasure centers. “#OverNightBag” is a grinding ballad that spotlights their seductive vocals, while on "#iWantDat,” rappers Problem and Bad Lucc help them cut loose over rubbery beats and huge handclaps.
