I've sent this out to some people but it is too good not to share, particularly if you like hard rock from the 1980s.
The setup: Microsoft has a research product that generates cheesy background music to a recording of your voice, in key. Here is a lame video of it.
The gag: Someone pulled the audio from a hard rock song to see what it would be like with a real singer, or in this case, David Lee Roth. It is pretty funny (click here).
