...of different songs with the exact same title? I'm sorta tempted to do a medley of the Cranberries, Pretty Reckless and Natalia Kills "Zombies". No "Walking With A Zombie" or "Zombie Dance" or any other variation, just all "Zombie" all the time. But that's only three songs. But I'm sure something much much longer is possible. Maybe you could do an entire 15-song set of songs all called "Dangerous"?
