"Oui mais... non" (English: "Yes But... No") is a 2010 song by French pop musician Mylène Farmer.

[1] On 28 September 2010, NRJ issued a press release announcing that "Oui mais... non" would be aired the next day on the radio, at 7.30 a.m.

[2] Immediately, many newspapers, including Le Parisien,[3] Ouest France[4] and Gala,[5] published the information, and many Internet sites did it also.

[6] On 22 October, physical formats with remixes by Tomer G, Klaas and Chew Fu were scheduled to be released on 29 November.

[10] In it, the singer appeared dressed in shiny black leather with a crucifix around her neck, and is surrounded by dancers performing a choreographed dance.

[9] On 11 October, Universal Music announced on its website that the song rocked atop of the digital chart after just a few hours.

To date, it has sold about 50,000 CDs and was downloaded legally more than 80,000 times, overall selling about 130,000 copies, thus being even more successful than Farmer's 2005 single "Fuck Them All" (which was released when the music market was in a better shape), and her biggest hit since "C'est une belle journée" (2002).
