It's not just you. That song is in every ad.

Temper Trap's "Sweet Disposition" is quite the popular song these days — among ad agencies, at least. It has so far been featured in ads for Chrysler, Rhapsody, the movie 500 Days of Summer, and most recently Diet Coke. As if that weren't enough, it has also been used in official conjunction with 90210, Greek, The Good Wife, and The Deep End. Some of the more attentive consumers are calling upon advertisers to find a new favorite song before this one attains sentience and enslaves humanity.
