The obvious differences from manga such as colour, movement and sound bring anime to life, but there is one additional element which is extremely important: the theme song. Artists from the J-pop and J-rock world are all falling over themselves to write the theme songs for the next big anime series as it is almost a guaranteed hit and provides great exposure. The anticipation of which artist it will be can often overshadow the anime itself, being the topic of hot discussion in school playgrounds and internet forums.
