According to Hanteo Chart, as of July 29th at 11PM KST, LOONA's 4th mini album '&' topped the real-time album chart. This month, LOONA abruptly suspended their '&' activities due to a confirmed COVID-19 case of a staff member. Despite this obstacle, LOONA's mini album '&' topped the album charts, proving their popularity.

LOONA's album '&' tells the story about how 'you' and 'I' break through the rigid rules and 'become one'. The mini album includes 7 different tracks, including their title track "PPT (Paint the Town)", an intro track "&", and their side tracks "WOW", "Be Honest", "Dance On My Own", "A Different Night", and "U R".

Meanwhile, after the mini album was released back in June, LOONA achieved the #1 rank on the iTunes Worldwide Chart for three consecutive days, and #1 on the iTunes Album Chart in 36 different regions, including the United States.
