Open-Source Music

I just downloaded a recording and sound-editing software called Audacity.  My brother recommended it to me; he has used it to do the sound-editing for some of his short films.  I've messed around with the software for only a couple of hours so far, but I have to say that I'm impressed.  Here's a little blues ditty that I recorded with nothing more than my guitar, my laptop, and a cruddy little webcam microphone.

So how much did this software cost you might ask.  It's free?  That's right...free.99 baby.  How is it that a product that would've been traditionally cost a small chunk of change...can now be given away?  Through the beauty of the phenomenon called "open-sourcing".  I love it.  Here's an interesting podcast about open-sourcing.  Enjoy...
