IPhone Volume Buttons: Too Coarse

Question

I have "feedback"ed several times over the years that, under the Music app, the volume up/down buttons provide too coarse volume-control resolution.  You get a total of only 16 steps to choose from, and I find that way too few.
Am I the only person who fells that way?  If not, I recommend you also feedback that to Apple.
Presumably Apple's counterargument is that you can adjust with very high resolution using the slider control.  I would agree with that sentiment, if people were using the app in the same way that they develop it – on a simulator running on a Macintosh, manipulating the control with a mouse. However, that does not work with thumbs on the iPhone itself, for two related reasons:  First, the slider is tiny compared to the size of a thumb, so the precision is … muddled … by that.  Second, and more importantly, as I remove my thumb from the screen, the slider setting almost always "jumps." 
In short, the buttons are the only high-precision way to adjust the volume, and with only 16 steps total, they don't give us any precision to work with.
Also, there's almost no downside to making he buttons more resolute, because hitting a button is trivially easy.  Finding the correct button?  Effort=2/10.  One click?  Effort=0.05/10.  Three clicks?  Effort=0.15/10. 

Answer 1

if (there exists a way to make the buttons change the volume more resolutely) {
   how?;
} else if (my description of my concern suggests that I'm using the buttons or Music app in general unideally) {
   tell me more;
// and either way...
if (you agree with my concern) {
   Please also tell Apple (http://www.apple.com/feedback/iphone.html);
