Don't Don (song) his solo part. "Don't Don" debuted in weak positions at most online charts. It won its first #1 recognition, the SBS "Popular Songs" Mutizen Song, on October 21, 2007, a month after its release. "Don't Don" won its second recognition on November 1, 2007 at M.NET's "M!Countdown", being the number one song of the week along with V.O.S.'s new single, "Everyday". Although the successful sales of "Don't Don" is reflected from the notability of the first single, "Don't Don" did not win as many achievements as the group's past single, "U".
