I probably missed something in this thread, but where are you going to
get an FM transmitter that isn't designed to work with FM radios?
A CB no-longer-wants-to-be?

Ok, facetious answer, but there's a point to
this, they do exist. For all I know, if the microtransmitters have slightly
narrower bandwidth deliberately to reduce encroachment on other signals (wise
maybe, given that many of these devices may be built and used), then the loss
of SNR and quality for music listening may be acceptable for some, but not to
me. I wouldn't use one if they haven't got good quality sound. If intended
for use in a car, there's much less likely a demand that they should.
