We know very little about the Prince That Was Promised, and this is, in fact, the primary source of debate within the fandom—largely because most people do not fully grasp the prophecy. So, what is this prophecy actually about?

Especially when you consider how Martin compares the fight against the Others to a “dance” in AGOT, it’s hardly surprising that the great war to come will be a song.
Aegon also chose a three-headed dragon as his sigil during the Conquest. The dragon had three heads, representing Aegon, Rhaenys and Visenya, so it’s hardly surprising that he also envisioned a three-headed dragon emerging from his own bloodline: a hero who would come after him.
