Microsoft Songsmith can turn your life into the musical from hell

The premise of Microsoft's newly-released music making application is simple – you just sing into your PC's microphone and Songsmith analyzes your song's notes to create a background track.  If you'd like to see all the ways you can use this power for evil, watch the video after the jump.

I'm going to warn you before you even get a chance to click the play button – in my eyes, this ad is already an early contender for "Worst Ad of the Year" in 2009.  What you're about to watch is so gosh-darn wholesome it's borderline criminal.  It may make you very uncomfortable.

Don't say I didn't warn you.

Songsmith is available now from for $29.95.  If you can eventually wipe the memory away of the video you just watched, it might be a cool application to play with.
