He makes some songs in French and some fans doing critics. I always hear Mika singing in english, and french fans not complaining about it, some fan undestand nothing because it's in english. For me it's not a problem because I love english. If a day he sing in spanish or italian I will love too if songs are good. In german I'm not sure because the only music I love in german it's Rammstein
But Mika said since a long time that he wants to make songs in french but that he had to find a good song writer.
It's just because France represente his childhood, french is his mother tongue, that why when he speaks french he speaks like a little boy (so cute ).
He has more success in France than in England or Germany or USA that's a fact, and I don't think he needs to sing in french to sell more records in this country.
He is attach to England too, especially to London, and I understand why I love England and London too.
I think all the critics in the fact that he make some songs in french is the result of a certain jalousy.
I read lots of fans comments in some threads and forums, saying why Mika speaks french in french concerts I remind to some people that he speaks spanish at spanish gigs
It's like when I was at the Hammersmith Apolo gig last year, the first night, I had on my left two Mika fans speaking and saying that they hope that the futur DVD will not be again filmed in France. I don't understand those kind of reactions, I'm happy to see a new DVD I don't care if it's filmed in England, Germany, USA, Brazil, Japon, Spain, Italy,....
