A >tempo difference of 125/124 can apparently affect the popularity of a tune. Er, I don't think so. Dance club DJ's like to "mix" different tunes together and segue from one to another without disturbing the beat. They speed up or slow down their turntables by considerably larger fractions than 125/124 to do this. >> But what if you had left the original tempo in place through the >> entire process, in one voice or a drumbeat?

One wouldn't necessarily have to keep the 3-against-2 going for long enough to hear the phase drift at each modulation. In fact, one could just switch to triplets suddenly, and later establish the basic pulse as an even number of these notes, without any drift occuring.
