If I was really industrious, I'd do this by running time, since there are so many lengthy songs.
These numbers aren't too surprising, except maybe the poor showing by Obscured. Some bad luck in the matchups, I think. This round, Sheep vs. PotW1 will ruin the perfect score for Animals, and there's a similar matchup on the horizon for Wish You Were Here. I've definitely learned to put more thought into the seeding next time I do a tournament like this.
