At the most basic level, it is a simple tap test; I've auditioned many a speaker where I could hear the artist's take a breath in and guess the length of the guitarist's nails, but was unmoved. The same music through a different speaker would make me tap my foot and nod my head saying, "yeah." That's musicality to me.
It is certainly possible to have both resolution and musicality (for lack of a better way of describing that which makes your foot start to tappin'). They are not necessarily exclusive one each other.
