I recently wrote a very in depth article on where one can find music for games. It's a very nice list of sources ranging from free sources such as the Newgrounds Audio Portal, to paid sources such as Somatones and other larger companies. If you're a flash game designer, or simply interested in various music sources on the net, definitely check it out.
In addition, I have a few games in the works right now. Two of them are on hold due to how long they'll take to complete, but another is in fast progress and I'm hoping to get it out by Halloween, we'll see how that goes.
Keep an eye out for the game later this month, and drop me a comment either here on the flash games blog pertaining to the music article, peace out,
