The jovial world of Rapture makes the perfect backdrop for a BioShock musical number. A man chooses but a slave JUST WANTS TO DANCE! YouTuber brentalfloss has composed this lovely BioShock song, a love song really, about Rapture. With lyrics like, "Hop in a bathysphere, take in the atmosphere, it's like New York, but with more fish," you know you're in for a good time.
Check out the YouTube page for the rest of the lyrics.
