Work for hire

According to a story repeated by Music Radar, Microsoft commissioned Brian Eno to compose the startup sound for Windows 95.  I seem to recall seeing Eno's description of the requirements of the job, something like "it has to be like *this*, it has to be like *that*... and it has to be six seconds long."  

For those six seconds, Mr. Eno pocketed a fee of $35,000.  Let me see, $350,000 a minute, and $350K X 60 per hour... I'm guessing he got a flat fee instead of royalties.  

And, according to the composer, he created it on a Mac.  And now you know... the rrrrrest of the story.
