So, Prince died 319-days after his 57th birthday, and "Three One Nine" connects to '57'.
The lyrics to the song are about a beautiful woman, which makes me think of the 'creator'.
'Three Hundred Nineteen' also has some interesting Gematria...
As does 'Three Nineteen'.
'319' also has a connection to '227', which connects back to 'Pi'.
Remember how Prince attended the Warriors game that finished with a sum of 227 points, 49-days before his death? I have a video on it.
Warriors = 49
227, the 49th prime
