I got ads that jingle, jangle, jingle.

Jingles are, by a wide margin, the most expensive copy I do.

Why?

Because they're worth it.

Jingles stay in people's minds forever. If I were to hum a few bars from a well-known jingle, classic or contemporary, your average person could finish the tune. Unlike slogans and logos and especially annual ad campaigns, jingles are a buy-once cry-once way to consistently generate a stream of leads that result in profit. Get a jingle means, to quote the kids, you're sitting on a mill.
