"Can You Feel It" by Mr. Fingers
This song isn't quite as sleazy as its name (and producer) would suggest, but it's pretty close. One can definitely imagine dirty things being done while "Can You Feel It"s bouncy synth plays naughtily in the background. The smooth cymbal hits and dreamy synth washes only help its porno feel. But dirty isn't necessarily a bad thing, and in the case of this song, it's definitely not a bad thing. It's actually a fun, danceable, minimal, intellectual, quintessentially Chicago thing.
