Microsoft Songsmith Rocks!!

Check out Microsoft Songsmith: http://research.microsoft.com/en-us/um/redmond/projects/songsmith/. We spent some time goofing with it this weekend to blow off steam during a 37-hour code-a-thon, and it's awesome. You sing (whatever comes to mind...) to a beat, and it then adds music to accompany your ramblings and off-pitch vocals. It's like karaoke without any rules, and I'm hooked. It says it's still a "Microsoft Research" product, and the video advertisement is hokey, but the product is almost as entrancing as Rock Band.
