A rapper, singer, and songwriter known for her work as one fourth of third-generation phenom MAMAMOO, Moon Byul made her solo debut in 2018 with the self-care affirmation pop single “Selfish.” On her fourth K-pop solo EP, 2025’s *laundri*, Moon Byul continues to sort through the emotional laundry. “Goodbyes and Sad Eyes” is a lighthearted pop-rock track about breaking free from a relationship. Each track has an associating item of clothing and wash instructions. For the lead single, Moon Byul assigns a blue tie and prescribes a “cold hand wash.” MAMAMOO is one of the rare idol girl groups that writes a majority of its own material, and Moon Byul is one of the most prolific songwriters of the group, with credits on over 100 songs. For *laundri*, Moon Byul co-wrote and/or composed all but “Goodbyes and Sad Eyes” and “DRIP,” including the R&B-infused love song “Cotton” and fan-inspired rock ballad “Take-off.”
