Well satanic messages and such are normally better hidden and actually subliminal, this is way too out in the open. I'm sure she did it for the fun of it, same reason why she would've thrown up the all seeing eye triangle for about 2 minutes of her new video.
I think it's all a metaphor referring to this song's descent down the charts.
Like the sun in the morning
And the moon at night
