Researchers at Goldsmiths University in London have delared Queen's iconic 1977 single, "We Are the Champions" as the catchiest song in pop music history.  The study looked at four factors which were "long and detailed musical phrases, multiple pitch changes in a song's 'hook', male vocalists, and higher male voices making a noticeable vocal effort."  Finsihing behind the Queen song in the study were The Village People's "YMCA," Sum 41's "Fat Lip," Europe's "The Final Countdown," and The Automatic's "Monster."
