Songsmith - I Must Have This Program!

This is totally hilarious and got me laughing. basically Microsoft is releasing a new piece of software called Songsmith, which automatically fills in background music to any tune you sing. To see what I'm talking about, have a look at this utterly dreadful video (one in a chain of so horribly self-aware ads).
If that hasn't put you off yet, then you have to see what some people have done with it! If you feed the vocals of a well known song into the program, you can see what a machine would do to some of the classic music of the last century. I especially like Roxanne!
