Since it looks possible that this tiebreaker could end up with a tied vote, I'd like to bring up what I'm thinking about doing if that does end up happening before the poll actually closes.
In the past, when a tiebreaker has ended up tied, I've gone by total vote count to determine which song goes out. Obviously, this being the first round, that doesn't seem like a valid option. That leaves two alternatives that I can think of: one is just to eliminate them both and consider them tied for last place, and the other is to track down someone who hasn't voted in the poll and get them to choose (potentially someone who isn't a fan of the band who would just listen once to each song and pick a least favorite).
Personally, I don't mind just killing them both. It's the first round, and I doubt that the survivor of this tiebreaker will get that far. But if y'all want me to track down an individual to break the tie in the event that this poll ends up tied (thus allowing one of the songs to survive, so if you're a fan of one of these songs and think it has potential to go further, you might want this), I'm perfectly willing to do that—just say the word. Fair warning, I'll likely go straight to a user who is very active and who I know is not a Maiden fan.
Of course, this poll could end up not being tied at all, rendering this whole discussion moot. I just noticed the possibility and wanted to have a plan about how to keep the survivor going smoothly and be transparent about it as well.
