Heyy all!
LOL first of all can I just say how annoying I feel, for reading this stuff about something that Mika doesn't want to talk about. I think he isn't just doing it for his own sake - he is trying to show that that shouldn't matter, and it doesn't define who he is or what he does.
Also, I would like to mention that he says he wrote Lollipop for his younger sister, telling her not to have sex. LOL I love him...
Stuck in the Middle apparently talks about his mother and grandmother (he said on MTV... If i remember correctly).
And we all know that Big Girl was meant as a theme song for the Butterfly Lounge.
Love Today, however, has a murky background. Mika said on one occasion that it was him trying to capture how happy he was at the time. On another (the french interview where he sings opera) the interviewer says he was living a love story.
I am unsure if these are all true, but I just thought I'd mention that perhaps you're reading to far into the songs.
Or, I could be completely wrong, and he just made up a little story for each.
