Voting. Round 4: "Into battle... and with a song!"

I liked the 3rd and 4th songs, and I voted for the 4th!
P.S.: I don't agree that the 4th song isn't a battle song; listening to it before a battle will immediately lift your spirits, and therefore boost your fighting spirit. With such a song, you can defeat any enemy!

Overall, all the girls did a great job, and the interpretations were interesting!
