They’re back! After topping the charts with “Wait (The Whisper Song)” in 2005, hip-hop duo the Ying Yang Twins shake up the dance floor with their new single “Fist Pump, Jump Jump” featuring Greg Tecoz. Produced by RedOne (Lady Gaga, Nicki Minaj), the energetic anthem was inspired by MTV’s hit show “Jersey Shore,” and is quite a departure from their raunchy material of the past. Take a shot of their new sound.
