Microsoft Songsmith creates an interesting song from just a voice recording (youtube.com)

Summary: Songsmith is "music" software that takes a voice recording, and from it builds chords, bass, drums, etc that fit with the melody. This example is Marvin Gaye singing "Heard It Through the Grapevine" and the result is quite interesting.

There are plenty of other redone classics on YouTube, most of them aren't that good, but they are all very, very interesting. The technology may not be that useful (sans for making pop music), but it certainly is impressive. Enjoy.

This is a much better promotional tool for songsmith than that 'internal' video microsoft put out a few weeks ago.
