I'm guessing here but you might be thinking of In a Moment by Brian D. Siewert.  According to Springfield Spotlight it is not available to the public.  If you don't think that's the song you were looking for you should check out Springfield Spotlight and see if you can figure it out.  There are several vids on YouTube that have In a Moment featured.  Here's one so you can check it out.  That's my best guess.  If this is the song, you should check out Nunook's blog here at SOC.   Good luck.
