Could it be anything else? Various pieces of music have been my ringtone for years, and it's one of the few DS games that I can play with the sound up. They're cheerful and upbeat most of the time, but when it needs to be it's somber or suspenseful, and leaves you with a clear sense of who the character or scene is.
(Yes this is really short, but really what else can I say about it?)
