To Jingle or Not to Jingle?

It dawned on me the other day that Dunkin Donuts' latest round of television commercials begs the question: Are their little tunes songs or jingles? Let's look at the facts. Jingles are in commercials. Jingles are brief. And aside from the fact that they don't make me vomit and want to kill myself, jingles are just like the flu: catchy. And these suckers are catchy. Fritalian? You know you sang it at least 3 times after you saw it. At least. But just being catchy doesn't make it a jingle because we all know that lame "Macarena" song and it's stupid dance were catchy, too. Okay, so clearly I have no idea. So I'm leaving it open to all of you jingle fans who I know read this blog. Right?
