The song mentioned in this oneshot is Eternity by Paul van Dyk, featuring Adam Young. It's probably best to listen to it while you read.
Heart Song
All the old radio stations had, apparently, frozen, when whatever disaster that had caused the world to be nearly empty had struck. They were still running, mysteriously, much like the water lines, and electrical system, but merely played the same song or CD over and over again, until some clever person found it, and started a broadcast of their own. They didn't know the names of the songs, referring to them instead by the channel they had found them on, or a favorite line. She'd always be fond of 85.2FM, who's familiar tune had helped her through several of the old test chambers, but one could only listen to the same song so many times.
Which was how, alone in the kitchen, she'd turned the dial persistently until she found something new.
The tune she eventually settled on was catchy, oddly soothing. She smiled as she rummaged through the cupboards for something to eat.
By the second time through, she realized she was moving to the beat, swift and smooth, and the smile blossomed into a grin.
By the fourth time, she swayed her hips as she chopped the vegetables, humming the melody to herself.
On the sixth, she allowed herself a twirl as she dropped several of the ingredients into a pan and put down the lid. She'd never been a girly-girl, but she did catch herself wishing for a skirt. One really couldn't appreciate the full joy of a twirl without a ridiculously flow-y piece of fabric to swirl around one's knees. She rolled her eyes at the silliness of the idea of prancing around her kitchen like a housewife, but still tossed in another after she put the water on.
After dinner, the music humming away in the background, she found herself wishing for something even more frivolous and stupid.
The woman who had beaten Aperture twice, the test subject who survived, the human who had done any and everything to save her own skin sat in her tiny kitchen, with music in the air, and longed for a dancing partner.
Chell is lonesome...
