I really like the song "Grave's Disease" by Matt Pond PA, because it has a distinct "zhwub-zhwub" rhythm throughout. It's the sound of being inside the womb, listening to a baby's heartbeat. Are there other songs that use this type of sound? [more inside]

I am using a stethoscope to control an art project so that a sculpture of LEDs responds in time to a user's heartbeat. I've started by buying a cheap stethoscope and jamming an electret mike into the tube and builiding a simple amplifier circuit (similar to this) to connect it to the line in on a PC. it works well, but the overall sound quality is not fantastic. I have noticed that there are a lot of more expensive stethoscopes out there and I wonder if I would get a substantial improvement in sound quality by using one of them? [more inside]
