>>12588176I think we are hardwired to enjoy rhythm because of our heartbeats.
Think of this: as far as musical tempos go, we cut off the slowest designations at around 60BPM, which is just about your average resting heart rate.
We max out somewhere around 200+, which afaik if your heart goes faster than that you die.
About double the resting rate (say 120bpm) is close to the rate of a typical gait.
We hear a beat being played at 120bpm, and it is extremely natural for us to get into it, groove etc.
