Unlike many religions, which reserve the greatest heights of joy and suffering for the afterlife, the faith of Meloetta believes that rewards and punishments can be experienced every bit as strongly in the world of the living through the power of music. At times, they have been accused of hedonism, for their emphasis on the joy of music contrasts strongly with more austere faiths, but in this regard they are in perfect emulation of their god, for Meloetta is a deity of wonderous songs and powerful emotions. Despite the dogmas espoused by some priests, Meloetta's mind is seen even by the devout as fundamentally unknowable, and which songs it chooses to sing has often surprised its believers.

Meloetta has many songs, all of which create extreme effects in the listener – at least when dealing with in-person performances, for although recordings can accurately reproduce the tune, they create at best faint echoes of the associated sensations. Yet the varied tunes are often mistaken for only two, for despite the myriad of emotions which individuals feel, a Meloetta's song can create only happiness or sorrow.

Of the two songs, Meloetta's song of happiness is far better known, as is the rationale for its worship. It is often heard, for Meloetta is not averse to descending from the heavens to reward its followers; they describe it as creating an incomparable ecstasy. Yet there have been times in history when Meloetta has chosen to sing its other song, either to its enemies or its faithful. This song fills its listeners with such despair that they prefer taking their own lives to listening to it in its entirety, and it is said that should anyone ever have a strong enough will to live to make it finish its sorrowful song, then Meloetta shall finally perish.
