It's actually quite straightforward to me.
I would use the term "accurate" as an objective term to describe how well a speaker reproduces the exact waveform as fed to it, without any frequency troughs or peaks or other tonal coloration. Such speakers are sought after as a monitors in recording and movie sound studios, as they allow engineers the best chance to know exactly what is being recorded, rather than a sound any particular listener prefers.
"Musical" is a purely subjective term, and speakers described as such generally color the sound in some way that is pleasing to the ear of certain listeners, and not others.
I recently switched from some older Infinity RS monitors which I'd descibe as pretty accurate, to some B&W's which to my tastes are warmer and richer sounding - to me more "musical".
