Kia vs. Fiat

My love for commercial jingles is back...and always for cars...

Kia ushered in my forever love for "Fort Knox" by Goldfish.  However!  Kia has competition now with a feel good song by Pharrell Williams.  I am embarrassed to admit that I have never heard of Pharrell.  However, I love the few seconds of "Happy" from the new Fiat commercial and, surprisingly, clever advertising for ABC's Good Morning America.

The question now is which is my favorite choice?  Quite the dilemma.
