It doesn't get smoother than Crush, who debuted his effortlessly polished vocals in 2014 with the impassioned album Crush on You. Since then, the soul singer has been spinning emotive tales of love and yearning over warm, welcoming grooves heavy on jazz-influenced bass lines, splashy cymbals and pensive piano. Always exploring new styles, Crush even briefly entered the power ballad arena with "Beautiful", his smash-hit from the series Guardian: The Lonely and Great God. Despite the sentiment behind his tracks, his style is easy-swaying R&B perfect for summer car rides with the windows down.
