Music is the first way that humans were able to communicate. Singing, instruments, stories told in lyrics is something as ancient as the human race itself, and it often takes center stage in different forms of media. Many different series are made or broken by their music and anime fans love to debate over the best anime soundtracks of all time. Everyone has a favorite opening for their favorite series and is willing to defend it to the death. Much of an anime's legacy lies in its music's ability to keep an audience in the moment emotionally.
