Orchestral Maneuvers on the Moon

"Almost four decades went by before lost recordings emerged that revealed something unsettling that the three Apollo astronauts had experienced while flying above the far side of the moon. The taped recordings contained "strange, otherworldly music coming through the Apollo module's radio," according to the upcoming Science Channel series, 'NASA's Unexplained Files.'

The unexplained 'music' transmission lasted almost an hour, and just before the astronauts regained radio contact with Earth, they discussed whether or not to tell Mission Control what they had experienced:

'It's unbelievable! You know?'
'Shall we tell them about it?'
'I don't know. We ought to think about it.'

There's a clip from the show on the Huffington Post article, but it is merely the first of two parts. Part 2 Is unlisted, but I found it here. I can't say I heard anything that resembles music, but, on the other hand, the astronaut's claims have never been successfully debunked.

Regardless of the answer to the anomaly, it begs the question: would SETI recognize an extra-terrestrial transmission if it was an alien musical composition?

Kind of like this:

And then again, remember this?
