The biggest problem with this line of thinking is that some people use it as an excuse to accept a certain skill level and not improve their playing. "It is OK that I miss notes because I play musically." This is total bull. I am not saying that one should not be happy with a performance because of a few missed notes. But players who use musicallity as an excuse to miss notes or as an excuse not to improve their technique are bad marimba players and should be mocked accordingly.
