My kids hijacked my computer for a while to provide musical accompaniment to what they call the Highland Games, wherein they throw small pillows at each other down a short hallway for hours on end. Hence, my numbers are little skewed, but Dragostea Din Tei by O-zone is still number one. (Better known to some as The Numa Numa Dance.) U2’s Vertigo is number two, and Over the Counter Culture by the Ordinary Boys is third.
