SAVE
Stronger (I had to save you because that song, for me, is the most danceable of the round, essay notwithstanding)
Shake It Off (Obvious choice, but the perfect choice)
OFF
The Hardest Part (I love this song, but I didn't really agree with your essay, and it's not danceable at all)
Your House (gorgeous song, but I'm offing you because it's really hard to dance to a song that's acapella. I also looked up "Your House dance" on YouTube, and the dances with the song had some instrumental involved in it

)
Biting Down (it's a good song, but there were better options for sure like A World Alone and even The Love Club)
