Y.M.C.A.
From The Crazy Frog Wiki
Y.M.C.A. is an unreleased track on Crazy Hits. Despite supposedly being on the United States version of the album, with many sources listing it as one of the tracks,[1][2][3][4] no actual recording or reupload seems to exist. It would be a cover of the 1978 single Y.M.C.A. by American disco group Village People.[5]
