That is the deal -- they play a song that was popular the summer that you were 16 and partying, you get that warm feeling of nostalgia, and the company's logo appears. Repeat until logo = warm feeling. Mission accomplished. Devious and outright mechanical, but effective.
I agree, but I also don't think that's a new development, been going on for a long time. Some of us have just reached the point in the process where we're the ones that now recognize the oldies that are being played in the commercials as "our" music.
