I don’t have any hard data to point you towards but quite a few people self report that they cannot visualize images at all. Most people do but like all things related to the mind there is a spectrum where in the extreme you can find people who can fly by a city in a helicopter once who can reproduce the cityscape, remember the correct silhouettes of hundreds of buildings, with pencils or ink with extreme accuracy. It’s not a stretch to suppose a similar spectrum exists with audiation (didn’t know this word before BTW!) in the general public with most people can more or less hear some sound in their mind but having multiple channels of music playing in time.. probably not most. I suppose people who get songs stuck in their heads are more able than most in that regard for sure.
