I can't think of any way that this title could be one of the songs we know about. The only people I could see singing a song titled "Powerful Magic" are Rumple, who we know isn't singing, and the Black Fairy, who hasn't been mentioned (and I don't think Jaime Murray sings). It could also work as an Evil Queen or Zelena number, but I don't think they would open the episode with them. Perhaps it's an instrumental? I've always thought that the opening number would be a group one about the wedding. In Once, True Love is described as the most powerful magic of all so maybe that's what "Powerful Magic" refers to, the true love betweeen Emma and Killian.
