[McDonald's] is willing to pay rappers $1 to $5 each time songs with the plug hit the radio, according to today's Advertising Age. McDonald's hopes to have its signature sandwich in several songs by summer.
I like the ingenuity displayed here; it's a cool idea from an advertising standpoint. If this catches on, I'm sure it will initially run to an extreme with product mentions and placements becoming obvious and annoying. Afterwards, I'm sure artists will figure out interesting ways to get the products involved in their work without being overly commercial. Or I hope they will.
