One-Hit Wonder Day

A celebration of the artists who had one hit and then disappeared. "Come On Eileen" by Dexys Midnight Runners. "Mambo No. 5" by Lou Bega. "Macarena" by Los Del Rio. "Who Let the Dogs Out" by Baha Men. These songs are played at every wedding reception in America, and nobody knows any other song by these artists. This is the beauty of the one-hit wonder: perfection once is enough.
