Change Ur World

"Change Ur World" is the thirteenth single by Japanese boy band KAT-TUN. It was released on November 17, 2010 by their record label J-One Records. The title track was used as the 2nd theme song for the Nippon Television TV Show, Going! Sports & News, which is co-hosted by member Kazuya Kamenashi.

Chart performance
In its first week of its release, the single topped the Oricon singles chart, reportedly selling 230,829 copies. KAT-TUN gained their thirteenth consecutive number one single on the Oricon Weekly Singles Chart since their debut with all their singles sold more than 200,000 copies and continued to hold the second most consecutive number one singles since debut with fellow Johnny's group, NEWS.

By the end of the year, "Change Ur World" was reported by Oricon to sell 264,303 copies and was later certified Platinum by RIAJ denoting over 250,000 shipments.

Plagiarism allegations
On November 30, 2010, independent artist AVTechNO! posted an entry on his blog expressing shock at the similarities between the first minute of KAT-TUN's track "Never×Over~「-」Is Your Part~" and his own work, "DYE", first released on February 1, 2010. Videos comparing the two works have been posted on video sharing sites such as YouTube and Nico Nico Douga, and have since gathered over a million views combined.

Never×Over~「-」Is Your Part~ is credited to a panel of composers who created member solo songs that had been released in the past. The song consists of old member solo songs put together in a new arrangement.
