For a few years, it felt like half the hits in the rap and R&B world opened with “Mustard on the beat, ho!” Pulled from YG’s 2011 track “I’m Good,” the short click is peppy and uptempo, perfectly in sync with Mustard’s simple, catchy instrumentals. Almost always, the phrase precedes a hook that will embed itself in your head after a single play with an irresistible melody carved out of just a few notes (see “Rack City,” “2 On,” “Who Do You Love?” etc.) Back in 2014, Mustard admitted on Power 106 that he considered dropping it, but the 2010s pop rap lovers out there thank him for not doing so. —Grant Rindner
