My home crowd is pretty good for dancing to just about anything. Classic rock, neo swing, rockabilly, top40 with a danceable beat or sometimes not; it's all fair game. I typically stick to "standard" fare, but later in the night is usually when the more eclectic music pops up.
I actually played the jazzy pokemon song at an out-of-town event last year. I was worried about the reaction, but the funny thing is that maybe only half the room noticed. A few of the kids were thrilled that they danced to the pokemon song and ran up to me asking who sang it. Another guy was really enjoying the song and grooving to it *until* he realized what it was, then got really mad

That same night I also played a gypsy jazz version of the Mario Bros 2 theme song. Those were the best WTF looks I've ever gotten.
I love those moments where I'm watching the dancers really getting into a song, then when the familiar refrain hits the dance literally stops and they just stare at me in bewilderment. This is usually followed by me shouting "Dance you monkeys dance!" and all returns to normal.
