KAT-TUN recently released their seventh single, "Don't U Ever Stop," on 14 May 08, which topped the weekly Oricon chart in its first week with a total of 381,672 copies sold. Along with LIPS, KAT-TUN holds the records for the two highest first-week sales in 2008. The single's sales included three limited editions, each with two solo songs from two members. First limited edition contain solos from Kamenashi and Taguchi, the second with Akanishi and Tanaka, and the last with Ueda and Nakamaru. The regular edition also contains each of the members' solo songs.

Their official first performance of this song was on 25 April 08 on Music Station Live, with their solo performances on 15 May on Music Station as well. During the MC segment of the same broadcasting, Kamenashi announced that two more days were added to their Tokyo Dome concerts for their 2008 tour, resulting in a total of four consecutive days in the Dome, Japan's most popular stadium. This marks a historic event in the Dome's history, which has been established since 1988, as KAT-TUN is the first artist to hold four consecutive days at the stadium. I am gonna grab a copy of this. ;)
