I actually found a promo song myself, but I needed to confirm it, then I forgot where I found it. 
*smacks joo* 
Nah, man, I'll bet we've all made mistakes in that vein. Years ago I started a spread sheet of found music. Sometimes I couldn't place it, sometimes I just needed to add my own cryptic notes, and I still let stuff get away from me. Which is why I've made a few cryptic notes in this thread on occasion. I was thinking of starting a 'Found music, lost bump' thread
I found another promo track, I actually had a request for it once but I can't find that post to reply to it

but then I may have been looking in the wrong place. Anyway...
Robot Chicken - Sunday Leadin Promo (robot w/woman's face)
title - "Timelapse Symphony"
album - The Beatdown VH028
composers - Joseph Saba, Stewart Winter
videohelper.com
side note: we currently have just one bump from this library. Since it is also available at the MusicinSync site that's what 'available from' I used. HOWEVER,
browsing at VH seems to be much easier. I think I may have run across another one that I didn't look up right away (you know how that goes) but I wasn't absolutely positive like I usually am. I have about ten albums left and I keep hoping that irritatingly popular VB promo from I think 2008 will show up along with the DRRR!!! promo track.
