DOTDOA looks into the depth of the internet, using your birthday as a guide, and pulls back a horoscope/numberoscope just for you. It reads your message aloud, and then plays music based on the forces that are influencing your day.
You may choose to have the music come to you from iTunes (you will need to provide some sample songs into the playlists that DOTDOA creates for you), or you may use Pandora and partake in public playlists that embody the themes established by your reading. You can even use your own Pandora playlists for a more personal sound, but still let the universe have a say in what you hear.
