Block B’s rapper Zico has achieved an all-kill on the digital music charts with his latest solo single “Well Done (feat. Ja Mezz).”

On February 13, the day of the song’s release, “Well Done” came at number one on various music charts, including Melon, Olleh Music, and Genie. The single dethroned Zion.T and Crush‘s “Just” from the top spot on many of them.

“Well Done” is a smooth hip hop track that fuses acid jazz and boom bap, featuring upcoming rapper Ja Mezz. It is a significant departure from his previous solo single, “Tough Cookie.” The music video for the song shows Zico performing in front of big crowds, along with footage of him working on his music.
