[casual_games] Game Music and Audio

[Teddy Wijaya]

Hi All.;-)

I am really interested to know how people here develop music and audio 
(scoring points, certain in-game events, etc) for your game.
If you outsource it to a 3rd party sound engineer, where to outsource and 
how does it normally work? (i.e: rate per song or rate per minute).
Is the 3rd party normally specialize in song only or they normally can 
handle both full song and additional audio?

Thousand thanks and best regards,
