Someone's playing My Sharona. Loudly. I know this, because I can hear it clearly enough to distinguish the words and the various instruments.
Through the wall.
Of course, part of this is that I've played the song on Rock Band enough to train my head in how it sounds, and therefore be able to fill in much of the song from assorted clues. It's really hard to tell how much is one or the other.
I had a similar experience last night, when we stopped at Qdoba (yay, quesadillas!) and, as we got out of the car, the radio was playing Here It Goes Again. I heard that song once before we got Rock Band. Now it not only gives me instant recognition, it makes my hands start doing the drums. (I play all the instruments, depending, but all the parts on that are simple enough that the drums are, apparently, to my mind the best for beating out randomly.)
It's one of the things games do: make triggered experiences. They teach a way of interaction, and then you start wanting to use that interaction. It's not just rhythm games - after I played Sly Cooper, I started figuring out how you'd travel through urban environments if they were levels. Jump on that gatepost, then over to the treebranch, and then up to that windowledge.. because it's a system of interaction that I internalized, and then it can be connected to other environments that use the same conceptual objects. Yeah, a tree and a polygonal tree aren't the same, but they're both trees - and making abstractions like that is easy for the mind.
It's a different song now - less recognizable, but just as interesting, because I'm pretty sure I don't know this song. My mind, though, keeps trying to match the bits heard through the wall. I'm hearing it less well - maybe they turned the volume down. Maybe I'm just filling in less from my head - but I'm pulling out little bits of the melody, the production, the rhythm, the voice, and identifying songs they're like; making little hypotheses about what I'm listening to, throwing them away a moment later as I find something else that conflicts.
(And it changes again, as I write; a drumbeat, demi-regular, with a strong rhythm and occasional (and seemingly erratic) doublebeats, with nothing else I can hear. It's clearly not a song I know; the partial-matcher is throwing up its hands, so I see a bit deeper. There's a part trying to analyze the patterns of when it's a double beat, when a single; more broadly, trying to predict the sound, because it's such a simple soundscape that it leaves me waiting for more, for detail and complexity and flow instead of this unadorned rhythm. I can faintly hear something else, now, a higher-pitched noise playing over and around the bass beats - but not enough for me to hear the song, just one little bit of the underlying instrumentation. It almost makes me want to try meditating to a beat like that - strong and demiregular, distracting bits of the mind to let the others come out and play.)
