T.O.P is the fourth and final single released connected to the animated series Sonic X. Performed by the Korean-Japanese rapping duo KP, it was the third ending theme to the show, and used from episode 40 to 52. When production on series 2 began, the song was replaced by the second ending theme to the show, "The Shining Road." The song features a lot of Japanese wordplay and puns throughout. <a href="https://www.last.fm/music/KP">Read more on Last.fm</a>.
