Songs in commercials.

I find many commercials annoying however one technique that i think helps catches someones attention is incorporating a catchy song somewhere in the commercial. I hate the education connection commercials however the song is always stuck in my head after i see it on tv. Wether you like the commercial or not if there is a catchy song somewhere in it you find yourself singing it later on. Two advertisements that came out during the Superbowl had actual songs in them which help make the commercial more of a hit if you ask me. One was the m&m commercial that had the song "sexy and i know it" in it and the other was the chevy commercial with the song "we are young". Every time these commercials come on tv these songs draw you into the commercial and later you start to associate the songs with the products without realizing it.
