K-On!! television series has been a remarkable anime. Not only did the antics/pranks pulled among the five girls portrayed the light-heartedness of school/youth, the series also introduced lots of remarkable songs. Songs that are commercial successes (constantly appearing on top 5 of Oricon charts on release) and songs that are memorable. The second ending theme song of the second season, "No, Thank You!", is especially memorable. Played in a rockable manner, this anguish-filled song celebrate the present and youth appropriately to the theme of the anime.
