48. Annie Mac, BBC Radio 1, DJ
Dublin-born DJ Annie MacManus – better known as Annie Mac – helms the power hours of Radio 1's dance-music programming, delivering cutting-edge tracks to a legion of devoted followers around the world on her eponymous Friday-night show (in addition to hosting a number of other specialty programs). Since hitting the air a decade ago, she's extended her influence as both a musical curator and DJ in her own right, dropping sought-after compilations, headlining top clubs and festivals, and building her "Annie Mac Presents" showcases into a global-events brand noted for fresh, diverse lineups (at SXSW 2014, she spotlighted Kelis, electronic producer Tourist, and rapper Le1f). Mac's AMP DJ tour expanded to the U.S. in March, bringing her current slate of faves to clubs across the country.
