Don't U Ever Stop

"Don't U Ever Stop" is the seventh single by Japanese boy band, KAT-TUN, and the first single from their fourth studio album, Break the Records: By You & For You. The single was released in four editions and as such features four different covers; the three limited editions featured two solo songs (and its instrumental tracks) from two members each.

The first single with no tie-ins to commercials or television dramas since "Real Face", "Don't U Ever Stop" was released on May 14, 2008 and became KAT-TUN's seventh consecutive single to debut at number 1. The single was the eight bestselling single in Japan according to Oricon for 2008.

Release and promotion
KAT-TUN performed the song on television for the first time on Music Station on April 25, 2008 and again on May 2, 2008. The group returned to the show on May 16 to sing it for the third time as part of a medley which included each of their respective solo songs. On May 11, Taguchi and Ueda appeared and performed the song on their kōhai Hey! Say! JUMP's variety show, ''Hi! Hey! Say, while Tanaka was a guest performer on HSJ's other show, Show wa Hey!

Two days later, the band debuted the song on their own show, Cartoon KAT-TUN—the same day the single was released in Japan.
