This little behavior will let you crossfade between MP3s. For those of you who don"t know what a "crossfade" is, its a musical term that means you fade one music source out while fading another one in. DJs use it all the time to fade out one record while fading the next one in. This behavior does the same thing except instead of records it uses MP3s. Cut and past the behavior below into a behavior script in your director project.
