Some people here make music for free, most don't, and frankly it's perfectly fair to ask for money for music. Don't underestimate how long it takes to make music... making one fairly long song takes some people (me included) collectively up to thirty hours, if not longer. A friend of mine takes around 80 hours to make just one long song. Sure, it takes others just around 10 hours or so, but you can't judge how long it takes since it's different for everyone, and still, I can speak for everyone when I say that making a good original decently-sized song isn't a matter of a few minutes of dicking around in a music program.
And these don't need to be estimations; I can literally bring up my project files and show you the message that says how long I've been working on songs. My three latest long songs took me 28 hours, 34 hours and 36 hours, if my memory serves me correctly... and those are just for individual songs, let alone a whole game soundtrack. Now whether it takes you a lot longer to make a flash game or not still won't negate the fact that all those hours amount to a hell of a lot of work and if you're making money partly out of that work, then learn to share. Or, of course, you can always try making music yourself. Maybe you can whip up something decent-sounding in a year or four.
So yeah, you're either trolling or being really dumb.
