The Crazy Frog spawned a worldwide hit single with a remix of "Axel F", which reached the number one spot in the United Kingdom, Ireland, Turkey, New Zealand, Australia and most of Europe.

"Axel F" (a remix of the 1980s Harold Faltermeyer song), was released on May 23, 2005 and became one of the most successful singles of the year 2005. "Axel F" debuted at number one in the UK, remaining there for four weeks. The song was then knocked off the charts by rapper 2Pac's single 'Ghetto Gospel'. Similar success took place in Australia and many parts of Europe, and the song remained on the charts for many months in various countries worldwide. However, the song apparently failed to catch on as well in the US and Japan, where it reached #50 and #48 respectively. The "Axel F" music video was produced by Kaktus Film and Erik Wernquist, and centers on the pursuit of the Crazy Frog by a bounty hunter. He reprises his role as pursuer of the Crazy Frog in all subsequent videos.
