Playlists featuring preferred music for the two frontrunners were published on a variety of blogs and social network sites on Thursday.
President Sarkozy, not surprisingly and perhaps diplomatically, had a song by his wife, the singer Carla Bruni, on the list.
His musical tastes also include French rocker Johnny Hallyday, the classic singers Charles Aznavour and Julien Clerc as well as Elvis Presley.
He wrote on his campaign website that the songs were those he likes and that "I take with me wherever I go."
The president's Socialist rival, François Hollande, also shared his musical preferences.
These included some more contemporary artists including Nolwenn Leroy, who became famous through a TV talent show, and Olivia Ruiz.
Hollande even made room for a British singer on his list, the Grammy and Brit award winning Adele.
His selection also included a song by France's most popular personality and Socialist supporter, Yannick Noah.
Noah, who is better known as a tennis player outside France, launched a successful new career as a singer after he retired from the game.
