Boxes being packed/shipped w/ catchy/rhythmic piano music

Ok, so I'm trying to think of an ad...I think this one goes back three or four years...it includes catchy/rhythmic piano music (I can even play the melody a little bit on my keyboard...but I don't have a way to record it to post on here! Maybe I can figure out how to do that and post it on here later!)

I vaguely remember seeing cardboard boxes being moved, packed, shipped, etc... on an assembly line (?)
I also seem to remember the commercial having to do with computer/software...

Here are my guesses so far:

Fedex/Kinkos
UPS
Microsoft: Intel II/III, Windows, Windows Vista, etc...

Any ideas? Let me know! Thanks!

Amazon.com or Overstock.com

Do you by any chance have a link/links to some possible ads? I googled Amazon and Overstock ads and couldn't find anything. Thanks!

Search for their ads on youtube as several results come up.
