According to the Billboard K-Pop chart that was released on September 28, Naul's "Memory of the Wind" from his solo album took the top spot.

Naul's first official solo album, Principle of My Soul is filled with lyrics that tell his personal stories. His title song, "Memory of the Wind" accentuates Naul's soulful voice as it proves Naul to be a vocalist conquering the charts, amongst idols.

The second place on the chart was G-Dragon's "Missing You," climbing up a step from last week, followed by "All for You," "Crayon," and "Lipstick."
