Question: What is the song that played at the end of the season finale of The O.C.? It also was in one of the early episodes. It was played a lot on the radio right after September 11th also. Is it on the O.C. CD by any chance? Thanks! — Katie, Atlanta, Ga.

Televisionary: That was the late Jeff Buckley's version of Leonard Cohen's "Hallelujah," found on Buckley's album Grace, Katie. And since one version or another of that song is the correct answer to so many questions about so many shows, I'm beginning to believe there's an unspoken rule somewhere stating that it's required whenever a producer or writer needs to punch up a heavy moment. (Not that there's anything wrong with that — it's a beautiful song.)

And for all the other people who asked about songs on that episode, others included Alexi Murdoch's "Orange Sky," Orquestra del Playa's "Montserrat," Iron and Wine's "The Sea and the Rhythm," and Jem's version of Paul McCartney's "Maybe I'm Amazed."
