Restock, Not really, a stereo system is meant to replicate recorded music. It produces sound. The music is in the recorded performance. I can hear the 'music' in a poor system or a very advanced system, even if the output from the speaker is rolled off, bloated, shrill etc.
As a descriptive term, I believe it is usually connected with someone's attempt to describe a system as smooth with a neutral to warmish tone. But, its just undescriptive as everyone has their own opinion of what sounds 'musical' to them. Some would strike my assumption that 'musical' connotes any warmth. That to be 'musical' it must be 'neutral', which of course to me would suggest that in their definition 'accuracy' equates 'musicality'.
Rather than 'musical' why not for example 'the upper bass/lower mid-range is a tad warmer than normal, the mid-range is smooth and transitions into the highs without any upper midrange emphasis, and the highs are detailed and airy with out being bright? (Or what ever combination of adjectives you care to decide to use which would define your use of the term 'musical').
Were you to use your own specific terms I could then apply my knowledge of the components in your system to decide whether or not your opinion would be useful to me, but when you just say its musical I really don't have a clue about what it is that makes it 'musical'.
To me saying a product is 'musical' is much the same as saying its a 'killer', 'beats all', choose your own superlative, but you get the idea.
I don't know if this makes sense to you, its JMHO.
