Here's a few past spots that I was a music supervisor on that I really enjoyed.
JCPenney - Aviator
This JCPenney commercial is one of my favorite spots I've worked on. This was the 2nd time in advertising history that a John Lennon song had been used in an ad (first time was "Instant Karma" for Nike). I did all the final music edits and I think I had chills the entire time while working on it.
Folgers - Happy Mornings
Crest - Puppets
