Hi, Chris- I understand the limiting nature of genre classification as well as its subjective nature, but I have a large collection of LPs and simply saying they represent "good music" is not helpful to me in organizing, acquiring or managing such a collection. I do cross genre boundaries all the time, and can go from modern classical to Dixieland or pre-Zeppelin "heavy" rock (now often labelled metal) which I do think is a misnomer. I'm not rigid in respect to the boundaries since I think it all crosses over in different ways, but the general categories have been helpful to me for these reasons. I can hear the strands of influence among different performers and compositions. As to what is "good," I'll leave that to the ear of the beholder or listener.
