The most pop-culturally significant song of all time ever in the history of universe?

Use: Lauren finally lands alone time with the clueless object of her affection, Stephen, and what comes on the car radio? Only the twosome’s favorite gem from the early '80s – well before either were born. Thank you, KOST 103.5! Car sing-a-long time!

Effectiveness? The song landed in iTunes’ top 10 downloaded tunes the week after the episode aired and later appeared on the “ Laguna Beach” soundtrack. Did the adorable moment score Lauren any play with Stephen? Not so much. But the audience swooned. Oh, delicious unrequited love.
