Will the series finale for GoT be titled "A Song of Ice and Fire"?

I have a vibe that the final episode of the show will be called "A Song of Ice and Fire" for some reason. What would it mean if that would be the case next season? Could it be a call back to the book series that inspired the tv show, could it be a symbolic theme to Dany and Jon getting married and (possibly) having a child? Or could it be meaning the mess that the war between dragons and white walkers had brought? Yet again season 8 hasn't been filmed yet but I am willing to bet a thousand dragon coins that the final episode will be called that.
