Less than a year after their third EP, K-pop girl group Itzy returned with their fourth short set, Guess Who. Much like contemporaries BlackPink, the quintet's combination of hip-hop-influenced dance pop and an empowering anthemic sound helped garner a wide international audience, resulting in an English-language version of Top Three smash single "In the Morning." Their crossover success also pushed this six-song effort onto the Billboard 200, their first appearance on the main U.S. chart.
